Answer:

A

Step-by-step explanation:

Consider the expression

6x^2y-3+x^2y+2xy^2+2xy-6

which both girls are given.

In this expression there are like terms:

  • 6x^2y and x^2y;
  • -3 and -6.

Combine the like terms:

6x^2y+x^2y=7x^2y;

-3+(-6)=-9

So,

6x^2y-3+x^2y+2xy^2+2xy-6=7x^2y +2xy^2+2xy-9

Correct option is A, Salina combined the x^2y terms correctly, but then left +x^2y term in her answer.

I did the first one I need help on this that’s all
Alenkasestr [34]

Answer:

m<A = 70 deg

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180 deg. Add the three measures and set equal to 180. Solve for x. then use the value of x and the expression for m<A to find the measure of angle A.

m<A + m<B + m<C = 180

5x - 25 + 2x + 10 + 3x + 5 = 180

10x - 10 = 180

10x = 190

x = 19

m<A = 5x - 25 = 5(19) - 25 = 95 - 25 = 70

Answer: m<A = 70 deg
