The equivalent expressions are 3(6x - 3) = 72 and 18x - 9 = 72
<h3>Equations and expressions</h3>
Given the equation below as shown;
3/5(30x - 15) = 72
Expand
3/5(30x) - 3/5(15) = 72
90x/5 - 15/5 = 72
3(6x - 3) = 72
Expand
18x - 9 = 72
Hence the equivalent expressions are 3(6x - 3) = 72 and 18x - 9 = 72

Answer:
22
Step-by-step explanation:
5t=99+11
5t=110
divide both side by 5 to find the value of t
Answer:
1. y+5=4x-40
2.y=4x-45
Step-by-step explanation:
To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4
Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45
Answer:
x=7,x=-2
Step-by-step explanation:
x^2-5x-14=0
x^2-7x+2x-14=0
x(x-7)+2(x-7)=0
(x-7)(x+2)=0
x=7;x=-2
