Answer:
c = -3
Step-by-step explanation:
Call the unknown c
c(x-3) +2x = -(x-5) +4
Distribute the negative sign
c(x-3) +2x = -x+5+4
Combine like terms
c(x-3) +2x = -x +9
Subtract 2x from each side
c(x-3) +2x-2x = -x-2x +9
c(x-3) = -3x+9
Factor a -3 from the right side
c(x-3) = -3(x-3)
Divide by (x-3)
c = -3
The right and left hand side need to be equal for there to be infinite solutions, so c = -3
Answer:
252 square inches
Step-by-step explanation:
Georgia needs 4 triangles, each of which has a base of 9 inches and a height of 14 inches. The area of a triangle is ...
A = (1/2)bh
so one face of Georgia's pyramid will have an area of ...
A = (1/2)(9 in)(14 in) = 63 in^2
Then all four faces will have a total area of ...
(63 in^2) · 4 = 252 in^2
_____
Comment on the pattern
The pattern shown includes the base of the pyramid. The problem text says the base is not included. We have assumed that the base is not included. (For Georgia's pyramid, a different pattern would be more to the point: see attachment.)
