-(1+x-y)(x-y-1)
Step-by-step explanation:
since both terms are perfect squares, factor using the difference of squares formula
a2 - b2 = (a+b) (a-b) where a = 1 and b= x-y
-(1+x-y)(x-y-1)
Answer:Factor by grouping.

Solve for m in the given equation: 3(m + 2) = -( 6- m) + 10
Answer:
m = -1
Step-by-step explanation:
3(m + 2) = -( 6- m) + 10
Distribute
3m +6 = -6+m +10
Combine like terms
3m+6 = m+4
Subtract m from each side
3m-m+6 = m+4-m
2m+6 = 4
Subtract 6 from each side
2m+6-6 = 4-6
2m = -2
Divide by 2
2m/2 = -2/2
m = -1

A traffic helicopter descends 142 meters to be 430 meters above the ground, as illustrated in the diagram to the
right. Write an equation to describe the situation using h as the original height of the helicopter. What was the
original height of the helicopter?
430m+142m=h
The original height of the helicopter would be 142m higher than what it just descendet to.

Step-by-step explanation:
Goal: For each spot you need to find the value associated with the column name.
Radius: half the maximum width of a circle
Height: The measure of how tall the cylinder is
Base Area: Can be found using the equation BA = π*r²
To find volume in terms of pi:
Only square the radius. Do not multiply the r² value by π. After squaring the radius, multiply it by the height of the cylinder.
Equation for Volume of a Cylinder = h*BA = h*π*r² =Volume
This can also be done in reverse if you know the volume and either the Base Area, the radius, or the height.
Simply do:
[tex]\sqrt{ \frac{V}{h*pi}} =r[/tex]
to find the radius
OR
[tex]\sqrt{ \frac{V}{BA}} =h[/tex]
to find the height
OR
[tex]\frac{V}{h} =BA[/tex]

1. You are saving to buy a bike that will cost at least $110. Your
parents give you $65 toward the bike. Write an inequality to find
how much money you have to save. Then solve the inequality.
Answer:
x ≥ 110 - 65
x ≥ 45
Step-by-step explanation:
x^2-10=0 solve for all real values of x
this is very hard lol pls help
so x^2-10=0
we add 10 to both sides of the equation x^2 = 10
then take the square root of both sides of the equation to eliminate the exponent on the left side x = ± √10
The complete solution is the result of both the positive and negative portions of the solution. x = √10 ,−√10
the result can be shown in multiple forms
Exact Form :x=√10,−√10x=10,-10
Decimal Form: x=3.16227766…,−3.16227766

evaluate (-5) to the power of 3
Answer:
(-5)^3 = -125
Step-by-step explanation:
(-5)^3
= (-5) × (-5) × (-5) = -125
= (-5)^3 = -125
(-5) to the power of 3 is just (-5) multiplied by itself 3 times so (-5) to the power of 3 is (-5)^3 which is -125
Step-by-step explanation:
it's quite easy to go around this problem.
first you gotta consider the negative (-) sign..
you know when a negative sign multiplies another negative sign you'll get a positive sign.
example
-5*-5= ?
since you know the negative sign would turn to a positive sign when they multiply each other.
and be mindful of problems with different signs like
−6×9, you'll definitely get a negative answer
Now to your question.
(−5)^3, if you're struggling with composite expression,all you need is to break it down to simplified form
since it's -5 raised to the power of 3
you can as well write it as -5*-5*-5 (pay attention to the negative sign). then go through with your calculations
if you do it correctly, you'll arrive at the answer
-125

The diagram shows a circle inside a rectangle....
Answer:
let [tex]x[/tex] = height of rectangle
Given:
height of rectangle = diameter of circlelength of rectangle = 3 × height of rectangleTherefore,
height of rectangle = [tex]x[/tex]diameter of circle = [tex]x[/tex]radius of circle = [tex]\dfrac{1}{2}x[/tex]length of rectangle = [tex]3x[/tex]Shaded area = area of rectangle - area of circle
Area of rectangle = length × height
= [tex]3x \times x[/tex]
= [tex]3x^2[/tex]
Area of circle = [tex]\pi r^2[/tex]
[tex]=\pi \left(\dfrac{1}{2}x\right)^2[/tex]
[tex]=\dfrac14\pi x^2[/tex]
[tex]\implies \textsf{shaded area}=3x^2-\dfrac14\pi x^2[/tex]
If the radius = 2 cm, then the diameter ([tex]x[/tex]) = 4 cm
Substituting [tex]x = 4[/tex] into the equation:
[tex]\implies \textsf{shaded area}=3(4)^2-\dfrac14\pi (4)^2[/tex]
[tex]\implies \textsf{shaded area}=48-4\pi[/tex]
[tex]\implies \textsf{shaded area}=4(12-\pi) \textsf{ cm}^2[/tex]

The ratio of 3 L milk to 800 ml of water is,
Step-by-step explanation:
You start with milk : water = 7 :3
Total volume = 800 mL
Volume of milk = 7/10*800 = 560 mL
Volume of water = 3/10*800 = 240 mL water
Volume of milk must remain constant at 560 mL which is 2 parts
Therefore 3 parts water = 3/2*560 = 840 mL water final volume
You need to add 840 mL - 240 mL = 600 mL water .
