Answer:
-3
Step-by-step explanation:
5*(-2 + a) = -25
Use distributive property,
5*(-2) + 5*a = -25
-10 + 5a = -25
Add 10 to both sides
5x = - 25+ 10
5x = -15
Divide both sides by 5
x = -15/5
x = -3

Answer:
E. V=225 cm^3.
Step-by-step explanation:
What you do is you use the formula for the volume of a pyramid which is V=lwh/3.
The length is 9 cm.
The width is 5 cm (but remember you have two.)
The height is 3 cm.
<em>V=9*5*5*3/3</em>
<em>V=675/3</em>
<em>V=225 cm^3. Is your answer. </em>

Answer:
A 3
Step-by-step explanation:
y-9 = 3(x-9)
This is in point slope form
y-y1 = m(x-x1)
where (x1,y1) is the point and m is the slope
A point on the line is (9,9) and the slope is 3
