3x + 2 = x + 4(x + 2).​

1 answer:
vesna_86 [32]3 years ago
7 0

Answer:

x = -3

Step-by-step explanation:

3x + 2 = x + 4(x + 2)

Get rid of the parentheses by using distribution

4 * x = 4x

4 * 2 = 8

3x + 2 = x + 4x + 8

Combine like terms

x + 4x = 5x

3x + 2 = 5x + 8

Isolate the x

3x + 2 = 5x + 8

-2             -2

3x = 5x + 6

-5x   -5x

-2x = 6

Now, simplify it

-2x = 6

----   -----

-2     -2

x = -3

____ [38]

Answer: 32 apples

Step-by-step explanation:

The ratio of apples to oranges sold is given as 4 to 2. Since Tia wants to sell a total of 48 apples and oranges, the number of apples that she should sell would be:

= 4/(4+2) × 48

= 4/6 × 48

= 32

Therefore, he should sell 32 apples.

Brian needs to find the value of a number, a, so that when (x^2+3x) is added to the binomial (3x^2+ax), the sum simplifies to 4x
Julli [10]

Answer:

a = 9

Step-by-step explanation:

First we need to add  (x^2+3x)  to (3x^2+ax),

(x^2+3x)+(3x^2+ax)

Expand

= x^2+3x+3x^2+ax

Collect the like terms

= x^2+3x^2+3x+ax

= 4x^2 + 3x + ax

= 4x^2+(3+a)x

Equate the solution to 4x^2+12x

4x^2+(3+a)x = 4x^2+12x

Comparing the like terms on both sides

(3+a)x =12x

3 + a = 12

a = 12 - 3

a = 9

Hence the value of a is 9
