Factor 21c+24.<br> Write your answer as a product with a whole number greater than 1.<br> use ()

Lera25 [3.4K]

Answer:

The required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$

Step-by-step explanation:

Given the expression

$21c+24$

Determining the factor

$21c+24$

Rewrite 24 as 3 · 8

Rewrite 21 as 3 · 7

so the expression becomes

$21c+24=3\cdot \:\:7c+3\cdot \:\:8$

Factor out the common term 3

$=3\left(7c+8\right)$

Therefore, the required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$

Answer:

Step 1: Distribute $-2$ to $5x$ and $8$

Step 2: Subtract from both sides of the equation $6x$

Step 3: Add to both sides of the equation $16$

Step 4: Divide both sides of the equation by $-16$

Step-by-step explanation:

Step 1: Apply the Distributive Property. Then you must distribute $-2$ to $5x$ and $8$

Then:

$-2(5x+8)=14+6x\\\\-10x-16=14+6x$

Step 2: You must apply the Subtraction property of Equality and subtract $6x$ from both sides of the equation. Then:

$-10x-16-6x=14+6x-6x\\\\-16x-16=14$

Step 3: You must apply the Addition property of Equality and add $16$ to both sides of the equation. Then:

$-16x-16+16=14+16\\\\-16x=30$

Step 4: You must apply the Division property of Equality and divide both sides by $-16$ . Then:

$\frac{-16x}{-16}=\frac{30}{-16}\\\\x=\frac{30}{-16}\\\\x=-\frac{15}{8}$
