Answer:
21
Step-by-step explanation:
To evaluate, substitute w = 6 into the expression, that is
15 + w = 15 + 6 = 21
Inches
centimeters would be too small
Good luck!
Step-by-step explanation:
(3x - 5)(2x + 1)
= 6x^2 + 3x - 10x - 5
= 6x^2 - 7x - 5
Answer:
4 units
Step-by-step explanation:
Create an equation where w is the width of the rectangle
Use the area formula, A = lw.
Since the length is the sum of the width and 1, it can be represented by w + 1
Plug in this and the area into the formula, and solve for w
A = lw
20 = (w + 1)(w)
20 = w² + w
w² + w - 20
(w + 5)(w - 4)
Solve for w:
w + 5 = 0
w = -5
w - 4 = 0
w = 4
Since the width cannot be negative, the answer must be 4.
So, the width of the rectangle is 4 units.
