(x+5)^2 = 2( 5x-3)\\x^2+10x+25=10x-6\\x^2+0x+31=0

ax^2 +bx +c=0

Formula for the discriminant:

D=b^2-4ac

b=0\\a=1\\c=31

<u>Corrected Question</u>

Matt makes $80 a month mowing lawns. His friend James also mows lawns, but he makes x dollars less per  month than Matt does. James makes a total of $816 per year. How much less each month does James make than Matt? Solve the linear equation to find the value for x

. Remember that x represents how much less per month James makes than Matt

Equation: 12(80 – x) = 816

Answer:

x=$12

Step-by-step explanation:

To solve the given equation

12(80 – x) = 816

First, we distribute:

960-12x=816

Collect like terms

12x=960-816

12x=144

Divide both sides by 12

x=12

Therefore, James makes $12 less than Matt every Month.

Find the missing factor 2x^2+15x+7=(2x+1)(?)
Genrish500 [490]

Answer:

? = (x + 7)

Step-by-step explanation:

2x^2 + 15x + 7 = (2x + 1) (?)

1. First you need to figure out what multiplied by 2x will give you 2x^2, which is x.

2. Then you need to find what would give you 15x. In this case because you have the 1 in (2x + 1), you already know that there is going to be an extra x. So, what times 2x gives you 14x? It's 7.

3. Lastly you need to make sure that 1 multiplied with 7 is equal to 7 and combine like terms.

4. Check: (2x + 1) (x + 7) =

2x^2 + 14x + 1x + 7 =

2x^2 + 15x + 7
