Find the values of x and y in the diagram.

x = 15 and y = 5

Step-by-step explanation:

since the triangle with the side 5y + 1 is am equilateral triangle and the other triangle with the side 26 is an isosceles triangle

5y + 1 = 26

simplify this to y = 5 and you have the value of y

for x

180 = 60 + 8x which simplifies to

x = 15

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
