Answer: 12.6 m
Step-by-step explanation:
Use the pythagorean theorem, we get that the height, or x, is
sqrt(22x22-18x18) = sqrt(484-324) = sqrt(160) = 4sqrt(10) = 12.6 m
Answer:
<h2>The width is (2x + 5) or (x - 3)</h2>
Step-by-step explanation:
The formula of an area of a rectangle:

l - length
w - width
We have


T = B + 3<span> T = B - </span>3<span> T = </span>3<span> - B T = 3B</span>
26) Answer is choice A: y = -3
This is the horizontal line that cuts the figure into two congruent pieces.

27) Answer is choice A: AB = 24 and DE = 12
CA/DF = 12/6 = 2
CB/FE = 20/10 = 2
The ratio of the larger to smaller corresponding sides is 2:1 or just 2
So AB needs to be twice as long as DE
That only happens with choice A
