Answer:
x=7
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
x+30−4x=4x+9−4x
−3x+30=9
Step 2: Subtract 30 from both sides.
−3x+30−30=9−30
−3x=−21
Step 3: Divide both sides by -3.
−3x
−3
=
−21
−3
<u><em>The sides of a rhombus are all congruent (the same length.)</em></u>
Answer:
3.6
Step-by-step explanation:
Using the area of rectangle formula L*W= A

Calculate the number of times the tent has to change hands:

The answer is A !!!!!!!!
the two segments AD and AB are equal therefore if you make the two equal to each other you will get the answer:
<span>x^2+2=11 then you subtract two to put x squared on the side by itself
</span>then you have <span>x^2=9
then all you have to do is take the square root of 9 and </span><span>x^2 and you get x=3
thefore the answer is A</span>
