Using the formulas
:
A=2AB+(a+b+c)h
AB=√(s(s﹣a)(s﹣b)(s﹣c)
)
s = (a+b+c) / 2
Solving for A:
A=ah+bh+ch+1
/2 √(﹣a∧4+2(ab)∧2+2(ac)∧2﹣b∧4+2(bc)∧2﹣c∧4)
=2·1.7+3·1.7+2·1.7+1
/2· √(﹣2∧4+2·(2·3)∧2+2·(2·2)∧2﹣3∧4+2·(3·2)∧2﹣24)
≈15.86863

Answer: the pitch of the roof is 2/9
It will be (7x+8)+(7x+8+7x=180
Answer:
5x+2
Step-by-step explanation:
Ok so the expression 5(x+2) is not 5x+2 because you have to use the distributive property. So with that being said:
5(x+2)=5 times x and 5 times 2
so the realest answer is 5x+10 instead of 5x+2
