Factor completely 10x2 + 2x − 8. (1 point)

Group of answer choices

2(5x − 1)(x + 4)

2(5x − 4)(x + 1)

2(5x + 2)(x − 2)

2(5x − 2)(x + 2)

Step-by-step explanation:

10x²+2x-8=0

=>10x²+10x-8x-8=0

=>10x(x+1)-8(x+1)=0

=>(10x-8)(x+1)=0

=>2(5x-4)(x+1)=0

Option B

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
