Answer:
d)X=4 or x=-2
Step-by-step explanation:
X²-2x=8
X²-2x-8=0
(x-4)(x+2)=0
X-4=0 or x+2=0
X=4 or x=-2
Its C. Add 3 and 15 which gives you 18. Then move the variable (4x) to the left. Then combine like terms which are the x’s and you should get 3x. Then divide both sides by 3. (18/3 = 6)
Y=3
x=-5
x=-5/2
x=-10

Answer:
37 7/33 or 37.212
Step-by-step explanation:
6j + 23 + k/l - 3
If j = 3, k = 7, and l = 33:
6 × 3 + 23 + 7/33 - 3
= 18 + 22 + 7/33 - 3
= 40 + 7/33 - 3
= 40 7/33 - 3
NOTE: Because 40 and 3 are whole numbers, 3 will be subtracted from 40.
= 37 7/33 or 37.212
