Answer:
x = 
Step-by-step explanation:
The segment from the vertex to the base is a perpendicular bisector.
Using Pythagoras' identity on the right triangle on the left.
x² = 2² + 3² = 4 + 9 = 13 ( take the square root of both sides )
x = 
(y x .12) x .3 = the total cost
15. (2•l)+(2•w)=38.
(2•l)+8=38.
Subtract 8 from both sides which leaves (2•l)=30.
Divide by 2 from both sides and that leaves 15.
3. g(x) = x^2 - 5x + 3
g(-3) = -3^2 - 5(-3) + 3
g(-3) = 9 + 15 + 3
g(-3) = 27 <==
4. 4(7b + 15f - 8f) =
4(7b + 7f) =
28b + 28f <===
5. C = 2.50r + 15
for 5 rolls...r = 5
C = 2.50(5) + 15
C = 12.50 + 15
C = 27.50...its A
