Answer:
69.1²feet
Step-by-step explanation:
area = pi x r²
11x2= 22
22x 3.14 = 69.08
69.1
✯<span>Let's solve this equation step-by-step!
</span>✯<span>is the question you've asked us today:
|x − 2| + 10 = 12
</span>✯<span>Add -10 to both sides:
</span><span><span><span>|x−2|</span>+10</span>+−10</span>=<span>12+<span>−10
</span></span>
✯<span>Solve Absolute Value:
</span><span>|x−2|</span>=<span>2
</span>
✯We know either:
<span>x−2=2 </span>or <span>x−2=<span>−<span>2
</span></span></span>
(Possibility 1) <span>x−2=2
</span>
(Add 2 to both sides) <span><span>x−2+2</span>=<span>2+2
</span></span>
x=<span>4
</span>
(Possibility 2) <span>x−2=<span>−2
</span></span>
(Add 2 to both sides) <span><span>x−2+2</span>=<span>−2+2</span></span>
x=<span>0
</span>
✯So since we have gotten x=4 and x=0 you answer shall be:
B. x=4 and x=0

Answer:
x = 192
Step-by-step explanation:
The three right triangles in the figure are all similar, so their sides are proportional.
<h3>Proportion</h3>
The length marked x is the long side of the smallest triangle, and the short side of the middle-size triangle. The long side of the middle-size triangle is ...
400 -144 = 256
We now have enough information to write the proportion ...
long side/short side = x/144 = 256/x
Multiplying by 144x gives ...
x² = (144)(256)
x = √(144×256) = 12×16 = 192
The length x is 192 units.
