Answer:
See below for answer.
Step-by-step explanation:
RP/RT =RQ/RS Given
∠R = ∠R
ΔPQR similar to Δ TSR If the measures of two sides of a triangle are proportional to the measures of two corresponding sides of another triangle and their included angles are congruent, then the triangles are similar.
Step-by-step explanation:
4x+10
If x=5
4(5)+10
=20+10
=30
Answer:
"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, where all you have to do is simplify; that is more of an order-of-operations kind of question
example: So let we are given a polynomial function as:
and we are aksed to evaluate this polynomial at 
Then the value of the polynomial will be:
Hence on evaluating the polynomial function f(x) at we get the value of the polynomial function as 
.
Because the perimeter is all the sides added:
P = side + side + side
4x + 3y = x + y + x + y + s
2x + y = s
Hope this helps!
