Answer:25x + 5
Step-by-step explanation:
(5x * 2 + 3x - 7) + (12x +12)
= (10x +2x - 7) + (12x + 12)
= (13x - 7) + (12x + 12)
Expand the brackets
= 13x - 7 + 12x + 12
Join like terms together
= 13x + 12x + 12 - 7
= 25x + 5

Answer:
(x+16)^2=20^2+x^2
Step-by-step explanation:
Given there was no bending of the tree, the Pitagorean Theory would help finding the value of the trees hight.
x^2+32x+16^2=400+x^2
32x=(20-16)×(20+16)
x=144/32
x=4m and 50cm
