Answer:
5. (x-8)(x+2)
10. (x-5)(x-5) OR (x-5)^2
-7
Step-by-step explanation:
2x+3=x-4
Let's start by subtracting 3 from both sides
2x=x-7
Now, subtract x from both sides
x=-7
Let's plug it in to make sure!
2(-7) +3= (-7)-4
-11=-11
y=-3x-3
Rotate 90 degrees
find slope
find y intercept
write equation
purrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
1. 6(3-8)-10
=6(-5)-10
=-30-10
=-40
2.30(3)+15(10)
=90+150
=240
3. 2(3)(3+32+32)
=6(67)
=402
