Question

How would I do -6(a+8)?

Community Answer

-6(a+8) = -6a-48, the number outside the bracket multiplies everything inside the bracket. i.e. (-6 x a) + (-6 x 8) = -6a - 48.

Question

Where do I put the parentheses in this equation: 6x+2-2x=4x+12?

Donagan

Top Answerer

On the left side of the equation, enclose "x+2" inside parentheses. It will look like 6(x+2)-2x=4x+12.

Question

How would I solve 9x15=(9x9)+(9x )=?

Community Answer

This is an effort to show you that you can rewrite a multiplication problem, using the distributive property. Instead of performing 9x15, you can break the 15 into smaller parts. In this case, someone has chosen 9 and the first part and you have to fill in the rest. Since 9+6=15, the blank space in your problem will be filled in with a 6. You will then have 9x15=(9x9)+(9x6). If you can resolve those two parentheses in your head and add them, you can do the solution. 9x9=81, and 9+6=54, so 81+54=135. Therefore the original problem 9x15=135.

Question

What do I do with a problem evolving two numbers being subtracted outside the parentheses like: Ten minus five Parenthesesnine n minus nine?

Community Answer

If the equation looks like this: 10-5(9n-9), then distribute the 5 to the equation inside the parenthesis it will look like this 10-45n-45. You would solve for N like a regular equation and the answer you will later get it:-35-45n.

Question

How do I solve 8x-3 (4-5)?

Community Answer

You may have copied this problem incorrectly. You cannot "solve" this expression, because it's not an equation. All you can do is simplify it. Perform the step inside the parentheses first. You will get 8x-3(-1). Then multiply the -3 by -1 to get +3. The simplified expression is 8x+3. Check your source to see if you miscopied the question.

Question

How do I solve 8(22) as a distributive problem?

Community Answer

Find the "difficult" number in the problem and rewrite it as the sum of two "easy" numbers. For example, 22 can be rewritten as (20+2). Then you can write your original problem as 8(20+2). Use the distributive property to get (8)(20)+(8)(2)=160+16=176.

Question

If I had the expression -8a(3b), then would the answer be -24a + 3ab?

Community Answer

Since you can't multiply a's and b's together, the answer would just be -8a x 3b.

Question

How do I use the distribution property to find the product of 7 and 16?

Community Answer

The distributive property can help you do some mental math and perform multiplication in your head. You can rewrite 7 x 16 as 7(10+6). Then the distributive property makes this fairly easy, as it becomes 7*10=70, and 7*6=42. Just add those two parts together, 70+42=112. Therefore the answer to 7x16=112. If you practice this you can quickly do multiplications in your head.

Question

Use distribute property to solve the following fact 8x6?

Community Answer

For single digits, I would not use the distributive property. You should just learn that 8x6=48. Some people like to use the distributive property using 10's. Therefore, instead of multiplying by 8, you would multiply by (10-2). Therefore, 8x6 turns into (10-2)(6). You can then use the distributive property to get (10)(6)-(2)(6)=60-12=48.

How do I solve the problem 4(y + 8)?

You can't "solve" this expression, because it's not an equation. But by the distributive property you can perform the implied multiplication to arrive at 4y + 32.

Question

How do you use the distributive property to solve 14x6?

Community Answer

When multiplying a number in the "teens," you can break it into 10 and whatever is left. This creates two simple multiplications that you can do in your head. Thus, 14x6=(10+4)(6). Then use the distributive property to rewrite this as (10x6)+(4x6). This is (60)+(24)=84.

Question

Can you show me how to do this problem: -6(b+2)+b-2(-4+6)?

Donagan

Top Answerer

The "b+2" is multiplied by the "-6" in front of it: that makes it "-6b-12." In the other parentheses, "-4+6" is the same as "+2." That's multiplied by the "-2" in front of it, making it "-4." The "+b" in the middle of the expression isn't multiplied by anything, so it remains unchanged. So you have "-6b-12+b-4," which simplifies to "-5b-16."

How do I solve 2(9x-8)=8(x-7)?

2*9x-2*8=8*x-8*7, 18x-16=8x-56, 18x-8x=56+16, 10x=72, x=72/10, x=36/5. So, the answer is x=7-1/5.

Question

How do I perform PEMDAS for (2x² +7) / 3 = 13?

Donagan

Top Answerer

Multiply both sides by 3: 2x² + 7 = 39. Subtract 7 from both sides: 2x² = 32. Divide both sides by 2: x² = 16. Find the square root of both sides: x = +/-4. (PEMDAS does not necessarily apply when solving an equation. It is applied mainly when simplifying expressions.)

Question

Given this expression: 60÷5(2+4), do I first perform 60÷5, then apply that result of 12 to the terms inside the parentheses? As in 12(2+4) = 24+48 =72. Or distribute the 5 first, 60÷(10+20)=2?

Community Answer

Do what is inside the parentheses first: 2 + 4 = 6. Next multiply and divide: 60 / [(5)(6)] = 60/30 = 2.
