Answer:

the answer is 1100. my dad has a math degree and this is what he told me.

Step-by-step explanation:

he told me that the figure has 2 shapes, a square and a rectangle but how many are their. we have 4 faces of rectangles and 2 faces of squares. so the squares equal 11*8 = 88 * 2 (because of 2 squares) which will give u 176, and the rectangle which is 11 * 21 = 231 * 4 (because of 4 rectangle sides) 924. now add them 924 + 176 is 1100

Answer:

$x^2 + x -12$

Step-by-step explanation:

If the solutions are x=-4 and x=3, then it must have factors (x+4)(x-3). Assuming there is no GCF or leading coefficient other than 1, multiply with FOIL to find the standard form.

$(x+4)(x-3)\\x^2 + 4x -3x -12\\x^2 + x -12$
