Answer:
(2x - 3)/(x +4)
Step-by-step explanation:
Given the expression 4x^2 - 9/2x^2+11x+12
Simplify the numerator
4x^2 - 9 = (2x)^2 - 3^2
Recall that a^2 - b^2 = (a-b)(a+b)
Hence 4x^2 - 9 = (2x - 3)(2x + 3)
The denominator
2x^2+11x+12
Factorize
2x^2+11x+12 = 2x^2+8x + 3x+12
=2x(x + 4) + 3(x + 4)
= (2x + 3)(x + 4)
Hence
4x^2 - 9/2x^2+11x+12 = (2x - 3)(2x + 3)/(2x + 3)(x + 4)
= (2x - 3)/(x +4)

Solve the equation below for X
1/3(-x + 3) = -x - 4
Solve the equation below for X
1/3(-x + 3) = -x - 4
Answer: x = -15/2 = -7.500

Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
1/3*(-x+3)-(-x-4)=0

Rewriting the whole as an Equivalent Fraction
3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 3 as the denominator :
-x - 4 (-x - 4) • 3
-x - 4 = —————— = ————————————
1 3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
STEP

:
Pulling out like terms
4.1 Pull out like factors :
-x - 4 = -1 • (x + 4)
Adding fractions that have a common denominator :
4.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero :
5.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
2x+15
————— • 3 = 0 • 3
3
Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
2x+15 = 0
Solving a Single Variable Equation:
5.2 Solve : 2x+15 = 0
Subtract 15 from both sides of the equation :
2x = -15
Divide both sides of the equation by 2:
x = -15/2 = -7.500
One solution was found :
x = -15/2 = -7.500

Sixty-four teams entered a citywide soccer tournament. Half of the teams are eliminated after each round. Write a function for the number of teams left after x rounds.
Answer:
x = (64 ÷ 2) ÷ r
Step-by-step explanation:
x = teams
r = rounds
hope this helps :)
Answer:
f(x)=-1/2x+64
Step-by-step explanation:
a function starts with f(x) so thats how i got the f(x) and im guessing this is talking about linear functions so they start of with 64 teams which is the y intercept and 1/2 are eliminated after each round which is -1/2 giving us f(x)= -1/2+64

Answer:
b, x = 17
Step-by-step explanation:
A right angle (as shown by the box in the corner of the angle) is 90°.
So, the two angles have to add up to 90°.
22 + 4x = 90
Subtract 22 from both sides.
4x = 68
Divide both sides by 4.
x = 17
The answer is b, 17
Hope this helps! Feel free to ask any questions! :)
Answer:
B.) 17
Step-by-step explanation:
90-22=68
68/4=17

A tree casts a shadow 21m long. The angle of elevation of the sun is 51º. What is the height of the tree? Round your answer to the nearest tenth.
Answer:
25.9
Step-by-step explanation:
If a tree casts a shadow 21 m long. Then the height of the tree will be 25.9 meters.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
A tree casts a shadow 21 m long.
The angle of elevation of the sun is 51°.
Let h be the height of tree.
Then the height of the tree will be
tan 51° = h / 21
h = 25.93 m

Marta told Maribel “The sum of fifty and half the number of oranges is the same as one-hundred-twenty.” Maribel wrote 50 (one-half) + m = 120 What is her error?
Answer:
Her error was that the half should have been multiplied by m, instead
[tex]50 + \frac{1}{2}m = 120[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = 50[/tex]
[tex]Rate = 0.05[/tex]
[tex]Days = n[/tex]
So, we have:
[tex]Base\ Amount + Rate * days = 120[/tex]
[tex]50 + \frac{1}{2}m = 120[/tex]
Hence, the error in her workings is that she should have pre-inform her before God and man.
Answer:
C - The One-half should be multiplied by m.

Find the surface
area of this figure.
2 in.
8 in.
[?] square inches
8 in.
5 in.
12 in.
10 in.
Answer:
528
Step-by-step explanation:
Surface area of bottom block + Surface area of top block - 2(Shared surface area)
Bottom block: 2(10*12) + 2(5*12) + 2(5*10) = 240 + 120 + 100 = 460 square inches
Top block: 2(2*2) + 4(2*8) = 8 + 64 = 72 square inches
Shared surface area = 2*2 = 4 square inches
Plugging into our formula:
460 + 72 - 4 = 528 square inches
