Can you put a picture of the full question please!
You have to distribute it or use FOIL (if u know that method). This is basically factoring.
for instance:
(2x-9)×(x+4)
first: 2x × x = 2x^2
second: 2x × 4 = 8x
third: -9 × x = -9x
forth: -9 × 4 = -36
now combine like terms.
2x^2 + 8x -9x - 36
(8x and -9x are like terms)
(add the two together, which is -1x or -x)
2x^2 -x -36 is ur answer
now do this same method for the rest
there is an limit of 2 people able to answer a question. so you need to find a question with 1 or less answers to answer it.
hope this helped
Answer:
x ≥ 56
Step-by-step explanation:
The whole problem will have to equal at least 120. If Xander has already collected 64, then he has a certain number of cans, x, remaining to collect. Since the problem is saying he needs "at least 120" then x and 64 must have a sum of at least 120. Thus you set up the problem like:
x + 64 ≥ 120
You can solve this simply by subtracting 64 from both sides.
x + (64-64) ≥ (120-64)
That would leave us with the answer:
x ≥ 54
Hope this helps!
