Add. (a2+6)+(4a+6) What is the answer?

Mathematics
1 answer:
matrenka [14]3 years ago

Look at the explanation to understand the answer.

Step-by-step explanation:

<u><em>Step 1.</em></u>

Rewrite (a2) in a2 + 6 so the <em>a </em>is before 2

(a2 + 6) + (4a + 6) ⇒ (2a + 6) + (4a + 6)

<u><em>Step 2.</em></u>

We'll need to organize 2a + 6 + 4a + 6 into groups of like terms, so we can combine them easier.

They're two groups of like terms in the expression.

First group: 2a and 4a

Second group: 6 and 6

Now, rewrite it so the 6 is added by the other 6.

2a + 4a + 6 + 6

<u><em>Step 3.</em></u>

We'll need to combine like terms in 2a + 4a + 6 + 6 by adding all the numerical coefficients and copying the literal parts, if any. No numerical coefficient implies value of 1. Numerical 'like' terms will be added.

We already know the groups with like terms.

First group: 2a and 4a

Second group: 6 and 6

Let's solve.

2a + 4a = 6a

6 + 6 = 12

Combine 6a and 12 up and you'll get your answer.

6a + 12 is the answer.

How come it’s a right triangle, I think you do a2+b2=C2. Therefore, you do 9.4 times 9.4 and then 15.1 times 15.1. So it will be 9.4 + b2=15.1. 88.36+ b2=228.01. Then you subtract that and it will be 139.65. Then you do square roots because you are trying to get rid of the second power. And the final answer is 11.81736011. How they told you to round it to the nearest tenth, I will be 11.8. I think this is the answer.

I need help with question a and b
DaniilM [7]

Solving for part A

f(x) = x^{2} \;\;and\;\; g(x) = \frac{1}{x^{3}} \\\\f(g(x)) = (\frac{1}{x^{3}})^{2}   =\frac{1}{x^{6}}

Domain of composition: x ≠ 0 i.e. Domain is the set of "Real numbers excluding number 0".

Solving for part B

f(x) = \frac{x}{x-2}\;\;and\;\;g(x) =\frac{3}{x} \\\\f(g(x))=\frac{\frac{3}{x}}{\frac{3}{x}-2}=\frac{\frac{3}{x}}{\frac{3-2x}{x}} =\frac{3}{3-2x}\\\\  Domain:\;3-2x\neq  0 \;\;OR\;\;x\neq \frac{3}{2}

Find 3 ratios that are equivalent to the given ratio. 36:42
drek231 [11]

Answer:

  • 6:7
  • 12:14
  • 96:112

Step-by-step explanation:

Each of the values in the given ratio is a multiple of 6. It can be reduced to lowest terms by dividing by 6. Then equivalents can be formed by multiplying the basic ratio by any number of your choice

  36:42 = 6:7

  = 12:14 . . . . . . . multiply by 2

  = 18:21 . . . . . . . multiply by 3

  = 24:28 . . . . . . multiply by 4

  = 96:112 . . . . . . multiply by 16
