5(3)-(-3)
15- (-3)
15+3 = 18
Answer:
-214.
Step-by-step explanation:
3x - 22y When x = 2 and y = 10 we have:
3(2) - 22(10)
= 6 - 220
= -214.
Let the width be x.
Width = x
Length = 4x + 7
The area is 650 m²
x(4x + 7) = 650
4x² + 7x - 650 = 0
Using quadratic formula:

a = 4, b = 7, c = -650


Width = 11.9m
Length = 4(11.9) + 7 = 54.6m
Answer: Length = 54.6m and width = 11.9m
Answer: The area is 5x + 20
Step-by-step explanation:
Add all the numbers up.
7 + 4x - 8 = 3
13 + (x + 8) = (x + 21)
Therefore, your answer is 5x + 20
