Answer:
1. C. Yes, because a sum of cubes can be factored
2a. false
2b. false
2c. true
2d. false (based on what is written in the equation; refer to step-by-step)
Step-by-step explanation:
1. Both 3 and 8 can be cubed, which is why x^3+8 can be factored (x+2)(x^2-2x+4)
2a. a^2-b^2 can be factored by the perfect square rule, so it should be (a-b)^2
2b. both terms are perfect squares, so you can factor, making it (a+b)(a-b)
2c. You can factor using the perfect square rule, making it (a+b)^2
2d. Most of what is in the equation is true, yet the correct solution would be (a-b)(a^2+ab+b^2)
Im not 100% sure but
A: 10
B: 5
C: 15
D: 30
for:
A: 30 x 1/3
B: 15 x 1/3
C: 5/ 1/3
D: 10/ 1/3
?
36/10? = 18/5 = 3.6 Are u sure that's the question?

Answer y=25/3 or 8.33333 and x=0.4444443
Step-by-step explanation:
y=4(y-7/3)+3 y=4y-28+3 y=4y-25
