Answer:
10 square units.
Step-by-step explanation:
Remark
No matter how weird it looks, the figure is a trapezoid. It has 2 parallel lines.
The height has 2 right angles, one at each end.
Givens
b1 = 2
b2 = 8
h = 2
Formula
Area = 1/2 * (b1 + b2 ) * h
Solution
Area = 1/2 * (2 + 4 + 2 + 2) * 2 Be sure you understand where all those 2s came from.
Area = 10 square units
Answer:
Step-by-step explanation:
x = 2
step-by-step explanation:
if sr parallel to ba then the sides bc and ac are in proportion, that is
\frac{sb}{cs} = \frac{ra}{cr} ← substitute values
\frac{4x+1}{2x} = \frac{13.5}{6} ( cross- multiply )
27x = 6(4x + 1)
27x = 24x + 6 ( subtract 24x from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Answer:
X=.5
Step-by-step explanation:
<u>First, I rewrite the equation:</u>
<u />
= ![\frac{x+9}{x}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B9%7D%7Bx%7D)
<u>Next, Cross Multiply:</u>
19x times x is 19x^2
x+9 times x+9 equals (x+9)^2
<u>Write the Formula Again, Revised:</u>
19x^2=(x+9)^2
<u>Square Root Both Sides:</u>
19x=x+9
<u>Subtract x from both sides:</u>
18x=9
<u>Divide Both Sides by 18:</u>
<em><u>X=.5</u></em>
.5 is the answer
i hope this helps!
