7 doesn't go perfectly into 60. So it can only go in 8 times and you'll have a remainder of 4. I hope this helped :)
perimeter = 2L + 2W
L=8+w
perimeter = 2(8+w) +2w
80 =16+2w+2w
80 = 16 +4w
64 =4w
w=64/4 = 16
l=16+8 =24
length = 24 feet
width = 16 feet
check 2(24) +2(16) = 48 + 32 = 80
(x-5)(x+4) is the factored version of this trinomial so if either of those values in the parenthesis are in the answer bank, choose those.
Answer:
12^2 + 15^2 = 18^2
Step-by-step explanation:
If we have 3 sides of a triangle we can use the Pythagorean theorem to determine if the triangle is a right triangle
a^2 + b^2 = c^2
12^2 + 15^2 = 18^2
If this is true, then the triangle is a right triangle
Test a pair from each table by substituting their values into the given equation and solving.
A) y = 2x + 1 .......... 2 = 2(0) + 1 .......... 2 ≠ 1
B) y = 2x + 1 .......... 1 = 2(0) + 1 .......... 1 = 1
C) y = 2x + 1 .......... -1 = 2(0) + 1 .......... -1 ≠ 1
D) y = 2x + 1 .......... -2 = 2(0) + 1 .......... -2 ≠ 1
The only pair that satisfied the equation was from answer choice B. Therefore, B is the correct answer.
