$0-(( \frac{1}{2} *y)*2y^3-8) \\ \\ then \ we \ would \ simplify \ 1/2 \\ \\ we \ factor y^3 - 4 \\ \\ 4 \ would \ not \ be \ a \ perfect \ cube. \\ \\ therefore, \ your \ answer \ would \ then \ be \ the \ following: \\ \\ \boxed{ -y * (y^3 - 4)}$

REGULAR 7TH GRADE MATH Slove each problem for x, showing all work

olga2289 [7]

Answer: x=27

Step-by-step explanation:

The degrees of any triangle are equal to 180

83+43= 126 so 126 degrees out of 180 are accounted for

180-126=54 this is what is left over to equal 2x

54/2=27 divide 54 in half, to get 27, (27x2=54)
