Answer:

QR=8

Step-by-step explanation:

so using the fact that the two triangles are congruent, we can determine:

5n-7=3n-1

5n-6=3n

2n-6=0

n=3

so we replace all n in 5n-7 with three

5x3-7

15-7

What is Y=2(3x+6)(5x-4)
Sliva [168]

Answer:

y=30x^2+36x+48 OR f(x)=30x^2+36x+48

This is an exponential function/exponential graph. Hope I helped!

Step-by-step explanation:

Given: y=2(3x+6)(5x-4)

Use the distributive property!: y=(6x+12)(5x-4)

Use the distributive property!: y=(5x(6x+12)-4(6x+12))

Use the distributive property!: y=(30x^2+60x)-(24x+48)

Remove parenthesis: y=30x^2+60x-24x+48y=30x^2+36x+48 OR f(x)=30x^2+36x+48

This is an exponential function/exponential graph. Hope I helped!
