bekas [8.4K]

Answer:

$\displaystyle 15\:feet\:wide \\ 32\:feet\:long$

Step-by-step explanation:

{2 + 2w = l

{94 = 2w + 2l

94 = 2w + 2[2 + 2w]

94 = 2w + 4 + 4w

94 = 4 + 6w

- 4 - 4

_________

$\displaystyle \frac{90}{6} = \frac{6w}{6}$

$\displaystyle 15 = w$ [Plug this back into both equations above to get the length of 32 feet]; $\displaystyle 32 = l$

I am joyous to assist you anytime.

If it doesn't give me the perimeter, how do i find x from this? thank you!

Mariulka [41]

The way the angles are labeled tell you that they are all congruent. The two triangles you see here also share the side that joins them. Then by the angle-side-angle postulate, the two triangles are congruent, so x + 23 = 13, or x = -10.

guajiro [1.7K]

SOLUTION:

We are to find the rate of inflation in the given question;

The formula to be used is;

Inflation rate =

$\frac{\text{CPI}_{present}-CPI_{previous}}{CPI_{previous}_{}}\text{ X 100}$ $\begin{gathered} \frac{221-208}{208}\text{ X }\frac{100}{1} \\ \\ \frac{13}{208}X\frac{100}{1} \\ \\ 6.25\text{ \%} \\ 6.3\text{ \% (nearest tenth of a percentage)} \end{gathered}$

CONCLUSION

The inflation rate of CPI that increased from 208 to 221 to the nearest tenth of a percentage is 6.3%.

Margaret [11]

Question:
l = 5 + w
perimeter = 22
width?

Solution:
Perimeter = 22
2(l + w) = 22
2(5+w+w) = 22
2 (5 + 2w) = 22
5 + 2w = 11
2w = 6
w = 3

The width is 3
