9(1+4x) what does x stand for?

1 answer:

8 0

"x", stands for a variable, in which any number can be placed inside. If there is an equal sign, x would stand for the number that solves the equation.

9(1 + 4x)

Simplify. Distribute 9 to both 1 and 4x

9(1) = 9, 4x(9) = 36x

36x + 9 is the same as 9(1 + 4x)

hope this helps

A rectangular garden has a length that is six feet more than twice its width. It takes 120 feet of fencing to completely enclose

vichka [17]

Step-by-step explanation:

let width = w then length, l = 2w + 6

$2w + 2(2w + 6) = 120$

a rectangular garden has two pairs of equal parallel sides 2w and 2l. here we multiply 2 by the width and 2 by the length which is given as 6 more than twice the width or 2w + 6. we then add these sides to get 120

$2w + 2(2w + 6) = 120 \\ 2w + 4w + 12 = 120 \\ 6w + 12 = 120 \\ 6w + 12 - 12 = 120 - 12 \\ 6w = 108 \\ \frac{6w}{6} = \frac{108}{6 } \\ w = 18$

check

$width = w = 18\\ length \: l = 2w + 6 = 2(18) + 6 = 42\\ w + w + l + l = 120\\ 2w + 2l = \\ 2(18) + 2(42) = \\ 36 + 84 = 120$
