Answer:
800
Step-by-step explanation:
Answer:
I think it would just be multiplying by 13.
First, we are going to draw an auxiliary horizontal line; next, we are going to place a protractor at the beginning of our line and draw a point at 60°. Now, we can use a ruler to measure 6 cm in our horizontal line and draw a solid line. Next, we are going to place our rule so the point at the beginning of the rule and the point at 60° lie on the same line; then we are going to measure 7 cm and draw a solid line. Last but not least we can join points A and C drawing a line.
Answer:
and are like terms.
Step-by-step explanation:
Recall what "like terms" means in an algebraic expression: Those terms that have the same variables at exactly the same exponents.
so in the expression: the second term and the fourth one are like terms. Notice that both terms have the variables: with the variable "x" to the power 2, and with the variable y to the first power.
and are like terms.
Therefore, those are the only terms you can combine to reduce the expression.
