Here you have an equilateral triangle. Because of this you know that all angles are also the same as each other. We know that the angles in an equilateral triangle are 60°.
so let's set 7x + 4 = 60
Subtract 4 from both sides: 7x = 56
Divide both sides by 7: x = 8
Answer:
F.
Step-by-step explanation:
20=4*5
9=4+5
Red line shows
y=x^2-4 , cause it's going through point (0,-4)
So blue line shows
y= -x^2+1 Point (1,0) belong to it , moreover x factor is negative , so the arms of parabola will go down
Have nice evenig :)

Answer:
Step-by-step explanation:
we will need to find the volume of the frosting
V=l*w*h
V=2(13*2*9)= 468 in^2 of frosting for the cake
528= 8x+240
288=8x
x=36 hours
