Equation 2:
3(18 - 3) = 45
step 1 do 18-3
now you have
3(15) = 45
and it’s just three, times fifteen.
3 • 15 = 45
Equation 1:
3x + 11 = 11
3x = 11 - 11
3x = 0 (divide both sides by 3 to get x)
3x/3 = 0/3
x = 0
Answer:
in the step-by-step
Step-by-step explanation:
okay one thing is that you labelled wrong since you have to label D', D", D'" (you just labelled with one for all of them)
a you reflected across the y-axis wrong
-it would be that D' (-2,6), E' (-2,3), F' (-5,3)
b you rotated correctly
this gets more confusing since you labelled the triangles wrong, but I hope this first part helps
Let x = your number.
x^2 - 21 = 4x. Subtract 4x from both sides.
x^2 - 4x - 21 = 0. Factor.
(x - 7) (x + 3) = 0. Set each term to 0.
x + 3 = 0. Subtract 3 from both sides.
x = -3. This is the negative solution.
Set the other term equal to zero.
x - 7 = 0. Add 7 to each side.
x = 7. This is the positive solution.
Answer:
c
Step-by-step explanation:
Hello!
3 x - 40^0 = 2 x - 10^0
3 x - 1 = 2 x - 1
3 x = 2x
3 x - 2 x = 0
Hence, the answer is 0
I hope this helps, and have a nice day!
