Angles A and B are complementary and the measure of angle A is twice the measure of angle B. Find the measures of angles A and B,
1) Complementary is defined as equal to 90 degrees. 2) A+B=90 degrees 3) We know that A is twice the measure of angle B. 4) We can represent A as being 2 measurements of B. 5) Our equation is now: 2B+B=90 degrees 6) Simplify the equation: 3B=90 degrees 7) Divide each side by 3 to simplify the equation to: B=30 degrees 8) Since A is twice the size of be our new equation is: 2B=A. 9) Substitute 30 degrees for B, we get 2*30=A 10) A=60 degrees.

Rewrite 5+5+5 as a multiplication expression.
First, count the number of 5's being added up. Next, since there are 3 of them that will be the first number in the expression. We are looking to take the multiplication of 5 three times. Therefore, our expression should be 3x5.
First, be sure to follow order of operations, so therefore we look at the two exponents which will give us: -36+4*9. Be careful with the negative sign in front of the 6, since it is not in parenthesis with the 6, it is not taken into account when looking at the exponent. Next, we will multiple 4 and 9 to get 36. Our equation should now look like this: -36+36 which equals 0.
