First you add like terms, so in this case it would be 2x+3x, which would together make 5x=10. Then to get x isolated divide 10 by 5 and x=2

You build and sell toy cars for $36 each. So far, you have built 25 toy cars. How many more toy cars will you have to build and

chubhunter [2.5K]

If you have built 25 cars, and they are 36 dollars per, then multiply 25 and 36 for the amount of money. This will result with 25*36=900. Since we already have 900 dollars worth, we subtract that from the goal of 1620, leaving us with 1620-900=720. Now, divide this by the price per car for the amount of cars needed to get to this goal. 720/36=20 cars

Hope this helps!

Which expression is a factor of 10 x 2 + 11 x + 3

Eduardwww [97]

Answer: the two factors are (5x + 3) and (2x + 1)

Explanation:

I will find the two factors of 10x² + 11x + 3.

You can use either the quadratic formula of factor.

I will use the quadratic formula:

1)

$x= \frac{b^2 +/- \sqrt{b^2-4ac} }{2a}$

$x= \frac{-11+/- \sqrt{11^2-4(10)(3)} }{(2)(10)}$

x = -3/5 and x = -1/2

2) the factors are: x - (-3/5) = 0 and x - (-1/2) = 0

Simplify them.

3) x - (-3/5) = 0

5x + 3 = 0

4) x - (-1/2) = 0

2x + 1 = 0

5) Then the two factors are: (5x + 3) and (2x + 1).

6) verify:

(5x + 3)(2x + 1) = 10x² + 5x + 6x + 3 = 10x² + 11x + 3 which is the original expression.

Priscilla built a cabanet shaped like a rectangular prism the lenght of the base is 9 inchesand the width is 40 inches what is t

Tomtit [17]

Answer:

360in²

Step-by-step explanation:

From the question,

L= Length = 9in

W= Width = 40in

Since, the base of rectangular prism is the same with Area of a rectangle. Then,

base of rectangular prism = ( Length × Width)

Then, Area of the base =( Lenght × Width)= ( 9 × 40)

= 360in²

Hence, area of the base of the cabinet = 360in²
