Answer:
x = 18
Step-by-step explanation:
7x - 26 = 5x + 10
7x - 26 - 5x - 10 =0
2x - 36 = 0
2x = 36
x = 18
this is non linear because the rate of change is not constant.
3rd answer
Step-by-step explanation:
for triangle HLM
180-2x
180-(3x+6)
H
2x=3x-10
x=10°
180-36=144°
36-20=16°
H=2x
H= 180-144-16= 20°
A)24 boards/1 * 47.5 inch/boards * 1 ft/12in = 95 ft.
according to dimensional analysis the answer is 95 ft.
b) 95/8 is approximately 12 so 12 boards are needed.
