The area of a triangular block is 36 square inches. If the base of the triangle is twice the height, how long are the base and the height of the triangle?

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.

0, because they don’t intersect

Simplify 7y+2x-10y+3x^2-10xfirst, combine like-terms(7y-10y)(2x-10x)(3x^2)-3y-8x+3x^2now put the coefficients in order3x^2-8x-3yyour answer is 3x^2-8x-3y
