Let y= how many lollipops he has left
Let x= how many friends he has
Answer:
x=48
Step-by-step explanation:
4x+5x+6x=180
15x=180
x=12
4x=48
Use y = mx+b Equation is Y=5x+5
Is this a Question???????
(If this is important then sorry for my answer)
Answer:
A: This quadratic expression can be factored by finding the correct pair of binomial factors
B: 4x + 5
B: 2x - 3
Step-by-step explanation:
8x² - 2x - 15 can only be factorised by finding a correct pair of binomial factors because 15 and 8 are not a perfect square.
Thus,
To find the correct pair, find the 2 numbers that would give us -120 (8*15) when multiplied, and would also give us -2 when added together.
(-12) × (+10) = -120
(-12) + (+10) = -2
-12 and +10 would be the factors to use. Thus, let's factorised as follows:
8x² - 2x - 15
8x² - 12x + 10x - 15
(8x² - 12x) + (10x - 15)
Look for common factors
4x(2x - 3) +5(2x - 3)
(4x + 5)(2x - 3)
