Ugh what is the area of this compound figure ?

5× 1/2 = ? a) more than 5 because you are multiplying by a whole number b) 5/10 because you multiply the numerator and denominator by 5 c) less than 5 because you are multiplying by a number that is more than 1 d) less than 5 because you are multiplying by a number that is less than 1

Plz ( true - false) all triangles have interior angles whose measure sum to 90.

Simplify the algebraic expression 8y-2(y+4)
