h² = 25So firstly, we must square root each side of the equation.(square root) h² = (square root)25.so... h= (square root)25.h=5. or h=-5.

(6x^2+4x-15x-10)(x+7)(6x^2 -11x-10)(x+7)= 6x^3-11x^2-10x+42x^2-77x-70)=6x^3+31x^2-87x-70

Put all the terms which contain x onto one side of the equation.-6 from both sides of the equation and -18x from both sides of the equation to get7xy-18x = 3y+7-6Simplify if possible7xy-18x = 3y+1Take the...

First, check you understand what the question's asking by determining the key words. Next, try a couple of examples to convince yourself that the statement does in fact work, i.e 1+2+3+4=10, which is even...
