The side is (2x+3)? then the area is:
(2x+3)(2x+3) = 4 x^2 + 12 x + 9 if x = 6 then
Area = 4(36)+12(6)+9
= 144 + 72 + 9
= 225, too big :(
Answer:
x > 6
Step-by-step explanation:
In order to determine volume you should multiple w*d*h. So in this case 5*6*3 or 90 cubic meters.
Answer: x=−10
Explanation:
1.regroup terms:4−x=−2x−6
2.add 2x to both sides: 4−x+2x=−6
3. Simplify 4−x+2x to 4+x.:: 4+x=−6
4. Subtract 4 from both sides: x=−6−4
5. Simplify —6−4 to −10: x=−10
I can help!! But could you tell me what the equations are?
