It would be doubled i think actually no just do the same equation with 4. i need to see the question first
Answer:
C. 40.5 cm²
Step-by-step explanation:
Use the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
The bases are the parallel sides, 4.5 cm and 9 cm. The height is the perpendicular distance between them, 6 cm. Filling in these numbers, we have ...
A = (1/2)(4.5 +9)(6) = 40.5 . . . cm²
X=-3 that’s the answer your welcome

Answer:
(- 4, 1 )
Step-by-step explanation:
Given the 2 equations
y = x + 5 → (1)
x - 5y = - 9 → (2)
Substitute y = x + 5 into (2)
x - 5(x + 5) = - 9 ← distribute and simplify left side
x - 5x - 25 = - 9
- 4x - 25 = - 9 ( add 25 to both sides )
- 4x = 16 ( divide both sides by - 4 )
x = - 4
Substitute x = - 4 into either of the 2 equations and evaluate for y
Substituting into (1)
y = - 4 + 5 = 1
Solution is (- 4, 1 )
