The perimeter of the rectangle is all the side lengths added up
Perimeter = 5 + 10 + 5 + 10 = 30
Hope that helps!
Answer:
Not a polygon
Step-by-step explanation:
[(3x+12)•(4x+4)]-(3x+8)-(4x)
[12x² + 12x + 48x + 48] - 3x - 8 - 4x
12x² + 60x + 48 - 7x - 8
12x² + 53x + 40
This is a degree 2 (quadratic) polynomial, not a polygon.
A polygon is an n-sided figure.
Example: A rectangle --> A four-sided polygon
Answer:
219 Seconds ; He was 1 second faster
Step-by-step explanation:
Two halfs equal one whole, meaning both of the times added will equal the full time he took:
95+124=219
219 Seconds
He was 1 second faster because:
219-218=1
Answer:
7/8
Step-by-step explanation:
Step 1: Change the denominators so that they are the same for both fractions
7/8 x 15 = 105/120
13/15 x 8 = 104/120
Step 2: Compare
104/120 < 105/120 = 13/15 < 7/8
Equation in slope intercept form: y= -1/2x + 3
