You will use the formula A=lw to find the area. Substitute 2x^3 in for the length and 4x^2 for the width. You would multiply both of these. 2×4 = 8, and x cubed times x squared equals X to the fifth power. You will add the exponents together because the exponent tells you how many times to multiply that value. If there are three x multiplied together (in x cubes) and two x multiplied together(in x squared) that makes five x multiplied together. The answer is represented as A=8x^5. ^ means to the power of.
<span>1/3x + 1/2y < or equal to 12
2x + y < or equal to 12
1/3x + 1/2y < or equal to 4.
Hope this helps!</span>
3 angles in a triangle need to = 180 degrees
so you have 2x+3x+4x = 180
9x = 180
x = 180/9
x = 20
Answer is A
The new area is (x-2)(y-2), the area is xy-2(x+y)+4, and the difference is 2(x+y)-4, which is 26. x+y=15, so the perimeter is 2*15=30 feet.
