How can I factor 5x^2 + 26x - 24 = 0 using the completing the square method.
Answers
— — — — — — — — — —
Step-by-step explanation:How can we factor 5x^2 + 26x - 24 = 0 using the completing the square method?
Let's solve your equation step-by-step.
[tex] \bold{Given \: Equation: \color{brown} 5x²+26x-24=0}[/tex]
First, add 24 to both sides.
[tex] \bold{5x²+26x-24 - \purple{ 24} = 0 + \purple{24}}[/tex][tex] \bold{ \implies \: 5x²+26x = 24 }[/tex]Since the coefficient of 5x² is 5, divide both sides by 5.
[tex] \bold{ \frac{5 {x}^{2} + 26x }{5} = \frac{24}{5} } \\ [/tex][tex] \bold{ \implies \: {x}^{2} + \frac{26}{5} x = \frac{24}{5} } \\ [/tex]The coefficient of 26/5x is 26/5. So, let b=26/5.
Then we need to add (b/2)²=169/25 to both sides to complete the square.
Add 169/25 to both sides.
[tex] \bold{ {x}^{2} + \frac{26}{5} x + \frac{ \purple{169}}{ \purple{25}}= \frac{24}{5} + \frac{ \purple{169}}{ \purple{25}} } \\ [/tex][tex] \bold{ \implies \:\bold{ {x}^{2} + \frac{26}{5} x + \frac{ 169}{ {25}}= \frac{289}{25} } } \\ [/tex]Factor the left side.
[tex] \bold{(x + \frac{13}{5} ) {}^{2} = \frac{289}{25} } \\ [/tex]
Take square root.
[tex] \bold{x + \frac{13}{5} = ± \: \sqrt{ \frac{289}{25} }} \\ [/tex]Then, add (-13)/5 to both sides.
[tex] \bold{x + \frac{13}{5} + \frac{\purple{ - 13} }{\purple{ 5}} = \frac{{ - 13} }{{ 5}} ± \: \sqrt{ \frac{289}{25}}} \\ [/tex][tex] \bold{ \: x = \frac{ - 13}{5} ± \sqrt{ \frac{289}{25} } } \\ [/tex][tex] \implies \: \underline{ \boxed{ \bold{ \frac{4}{5} } \sf \: \: or \: \: \bold{ x = - 6}}} \\ [/tex]_______________❖_______________
Eric is designing a logo for a company. The logo consists of two identical parallelograms joined at their longest sides. One of the parallelograms has a base of 2.5 centimeters and a height of 1.25 centimeters. What is the area of the logo
Answers
Answer:
6.26 cm
Step-by-step explanation:
To find the area of a parallelogram, the formula is just
B * H
so the equation would be
2.5 * 1.25
which would equal
3.13
Since in the question, the logo consists of two identical parallelograms, you would multiply 3.13 by 2 so the equation would be
3.13 * 2
which would equal
6.26

Two angles are complementary. One angle is equal to x + 6 degrees. The other is 3x +9 degrees. What is the measure of x?
Answers
Answer:153
Step-by-step explanation:3x9=27 so then you do 180-27=153 then 153 is your answer i'm sorry if this is incorrect
Hey there!
=> x + 6 + 3x +9 = 90°
=> 4x + 9 + 6 = 90°
=> 4x + 15 = 90°
=> 4x = 90° - 15
=> 4x = 75
=> [tex] \frac{4x}{4} = \frac{75}{4} [/tex]
=> [tex]x = \frac{75}{4} [/tex]
=> x = 18.75
Then ,
=> 18.75 + 6, 3(18.75) + 9
=> 24.75, 65.25
Therefore, the two angles are 24.75 and 65.25

Answer:
1920 cm³
Step-by-step explanation:
The volume of a cuboid is the product of its dimensions:
V = LWH
__
These two cuboids have the same width and depth, so can be stacked on top of each other to give a cuboid with the dimensions ...
(14 +10) = 24 cm high
8 cm deep
10 cm wide
Then the volume is ...
V = LWH = (8 cm)(10 cm)(24 cm) = 1920 cm³
The total volume is 1920 cubic centimeters.

25.6 x 0.4 = 10.24
and
10.24 ÷ 0.4 = 25.6
So, if we are trying to find the base of the first triangle we would do

Joey dirves his car 80 miles per hour on the highway. Write an equation that ralates his distance traveled (d) to the time elapsed (t)
Use your equation to determine how many hours it will take joey to travel 320 miles
Answers
Answer:
d=80+t
Step-by-step explanation:
An equation that relates his distance travelled (d) to the time elapsed (t) is d = 80t and the time taken to travel 320 miles is 4 hours.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Joey drives his car 80 miles per hour on the highway.
For 1 hours, the distance travelled is 80 miles,
For t hours, the distance travelled will be 80t miles.
So, distance, d = 80t, which is the required equation.
When the distance is 320 miles, the time taken to travel it is,
t = d / 80
t = 320 / 80
t = 4 hours
Hence the time taken to travel 320 miles is 4 hours.

Step-by-step explanation:Technology: Many of the problems in this book require the use of technology (graphing
calculators, computer software, or tablet applications) in order to solve them. You are
encouraged to use technology to explore, and to formulate and test conjectures. Keep the
following guidelines in mind: write before you calculate, so that you will have a clear record
of what you have done; be wary of rounding mid-calculation; pay attention to the degree of
accuracy requested; and be prepared to explain your method to your classmates. If don’t
know how to perform a needed action, there are many resources available online. Also, if
you are asked to “graph y = (2x−3)/(x+1)”, for instance, the expectation is that, although
you might use a graphing tool to generate a picture of the curve, you should sketch that
picture in your notebook or on the board, with correctly scaled axes.

Given that the three triangles are similar, we can make of geometry properties for similarity to determine the length of the missing line segment.
In this question we must find a missing length by similarity properties, which is represented mathematically by proportions. From the figure we have the following relationship:
5/y = (5 - x)/(5 - y) = x/1 (1)
From (1) we have the following two formulas:
