Replace the value of x and y into the equations and see if they solve:

x = -5, y = 24

24 = 0.28(-5),  24 = -1.4 False
24 = 0.28(-5) +3.6, 24 = 2.2 False

-5 = 3.6(24), -5 = 86.4 False
 none of the given equations work, so there is no direct variation

Hello!
----------
There is no direct variation in the age and height.
----------
WORK: 0.28*-5= -1.4
             0.28*-5+3.6=2.2
             3.6*24=86.4

Hope this helps and have a great day!

PLEASSEE HELPPPP HURRRY FIND THE SURFACE AREA HURRRYY
Aleksandr [31]

Answer:

The answer is 48.9 cm^2.

Step-by-step explanation:

Let's find the surface areas of the faces other than the base;

triangle area: b x h / 2

4 x 7 = 28, 28/2 = 14

in this case, there are three faces, so 14 x 3 = 42, and we add that with the base to get 48.9

:) hope this helps!
