Answer:
6.928 or 6.93
Step-by-step explanation:
\sqrt{8^{2}-4^{2}}
The triangle's base is 9 inches.
The area of a triangle is calculated with the base × perpendicular height × .
We already know the area is 18 square inches and the perpendicular height is 4 inches, so we can calculate the base.
4 × b × = 18
2 × b = 18
b = 18 ÷ 2
b = 9
(1/2)(n-4)-3=3-(2n+3)
n = 2
but if it is
(n-4)-3=3-(2n+3)
n = 7/3
49
substitute b = - 6 and c = 7 into the expression and evaluate
c - 7b = 7 - (7 × - 6) = 7 - (- 42) = 7 + 42 = 49
