Answer:
w = 18; l = 62
Step-by-step explanation:
The formula for perimeter of a rectangle is P = 2l + 2w, where l represents length and w represents width
We know that the length can be found using the equation l = 3w + 8
Plugging this in for l in the original formula for perimeter gives us 160 = 2 * (3w + 8) + 2w
160 = 6w + 16 + 2w
160 = 8w + 16
144 = 8w
18 = w
Plugging 18 in for the second equation gives us 3 * 18 = 54 + 8 = 62 = l
Answer:
74
Step-by-step explanation:
370 / 5 = 74 so she can only make 74

Answer:
D, 22x^9
Step-by-step explanation:
Here's a key for end behavior: Look at the leading term
x^even = x -> neg inf, f(x) -> pos inf; x -> pos inf, f(x) -> pos inf
-x^even = x -> neg inf, f(x) -> neg inf; x -> pos inf, f(x) -> neg inf
x^odd = x -> neg inf, f(x) -> neg inf; x -> pos inf, f(x) -> pos inf
-x^odd = x -> neg inf, f(x) -> pos inf; x -> pos inf, f(x) -> neg inf
Answer:
false
Step-by-step explanation:

Both of the matrices are 1 x 1 ("one by one"), so they can be added to produce a 1 x 1 matrix.
To add (or subtract) two matrices, they must be the same size.
(m x n) + (m x n) = (m x n)
m x n means a matrix has m rows and n columns. Dimensions are always named in that order: rows, then columns.
