How do you put this in simplest form?

Answers

Answer 1

Answer: Ok so this is a polynomial we are solving for so in this example we will have to set it up in box method and when I say that I mean 2x+7 on top and on the side or left hand side will be 3x-5 so lets solve so 2x times 3x is 6x^2 then on the right hand side we know 7 times 3x is 21x. Let's move on to the box on the bottom so now lets multiply 2x times -5 which is -10x then the last box we will have to multiply 7 times -5 is -35. So now we have to combine like terms which means combining the x's and the constants . So we leave 6x^2 alone and add -10x + 21x so since they have different signs we subtract which would result in 11x . Our final answer should be 6x^2+ 11x-35. Hoped this helped !! and remember to do the box formula to get credit

Answer 2

Answer: (2x+7)-(3x-5) you first distribute the negative sign to the 3x-5, making the expression 2x+7-3x+5, which simplifies to -x+12

1.5 gallons = x quarts

Answers

Given:
1.5 gallons = x quarts

1 gallon is equal to 4 quarts. 1 gal = 4 quarts

1.5 gallons * 4 quarts/gallon = 6 quarts.

There are 6 quarts in 1.5 gallons.

The value of x is 6.

Hence, 1.5 gallons = 6 quarts

The given statement is,

1.5 gallons = x quarts

Here we have to find how many quarts in 1.5 gallon

Since we know that,

A gallon is a standard measurement of volume and capacity for measuring liquids.

It is often used in Imperial systems and US customary measurement standards. Gallon is abbreviated as gal.

And we also know that,

1 gallon = 4 quarts

There for to find quantity of quarts in 1.5 gallon

Multiply both sides by 1.5 we get,

1.5 gallons = 4x1.5 quarts

= 6 quarts

Hence,

The value of x = 6,
