Answer:
if you solve the equation it is 8 but the equation is 5-(-3) or 5+3 because two negatives equal a plus
Answer:
GE = 14
Step-by-step explanation:
3x + 5 = 6x - 4
x = 3
Plug it in.
3 (3) + 5 = 14 = GD
6 (3) - 4 = 14 = GF
With that information, you know all the blue lines are the same.
GE = 14
Answer:
sail a = 81ft²
sail b base = 12ft
Step-by-step explanation:
question 5:
the measurements for sail A are 18ft(height) and 9ft (base)
the formula to find the the area of a triangle is (b · h) 1/2
(9 · 18) 1/2 = (162) 1/2 = 81
so ahmad will need 81ft² of fabric for sail a
question 6:
we know that the formula to find the area of a triangle is (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.
(b · 18) 1/2 = 108
= 108/ 1/2
(b · 18) = 216
18b = 216
18b/18 = 216/18
b= 12
check your work:
(12 · 18) 1/2 = 108
(216) 1/2 = 108
108 = 108 true!
the base measurement for sail b is 12ft
hope this helps and have a great day!!
