The area of a rug, which is shaped like a rectangle, is 4x²+4x square feet. factor this polynomial to find expressions for the dimensions of the rug

The dimensions of the rug would be 4x and x+1.

To factor this, we take out the GCF.  The larges factor that both coefficients have in common is 4.  Both factors also have an x, so we factor both out:

4x(     )

Taking 4x out of 4x² leaves x:
4x(x     )

Dividing 4x by 4x leaves 1:
4x(x+1)

D. 10x is the correct answer a and c are the common factor of 30 and 20 but it’s not the greatestonly b and d are the answers since 30x^3 -20x20x only have one x and 30 have 3 xso it can only be d.10xhope this will !

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°
