Answer:
40 in
Step-by-step explanation:
For a width of w, the length is 3w and the area and perimeter are ...
A = LW = (3w)(w) = 3w^2
P = 2(L+W) = 2(3w +w) = 8w
We are given the area, so we can find w to be ...
75 in^2 = 3w^2
25 in^2 = w^2 . . . . . divide by 3
5 in = w . . . . . . . . . square root
Then the perimeter is ...
P = 8w = 8(5 in) = 40 in
7/8=x/48
x=(7/8)48
x=(7)(48/8)
x=(7)(6)
x=42

Answer:
OMG you are so pretty
Step-by-step explanation:
If 61 is less than 8 times the number then the number is 8.
Given 61 is 3 less than 8 times the number.
Let the number be 'x'.
The term "polynomial" in mathematics refers to a mathematical statement that consists of two or more algebraic terms that are added, subtracted, or multiplied (no division!). Constants and positive exponents are frequently used, together with at least one variable, in polynomial formulas.
we can write the equation as:
8x ₋₋ 3 = 61
arranging the like terms i.e constants.
8x = 61 ₊ 3
8x = 64
to find the value of x, divide 64 by 8.
x = 64 ÷ 8
x = 8
hence the number we get after solving the equation is 8.
