Answer:
for what equation?
Step-by-step explanation:
1) D
(2/9) x=24
2) C
6x4=24
24=w
W=1/4(6)
3) A
67=9n
67=9n-2
9n-2=67
4) D
C+2x+x-3=56
4x=59
X=14.75
Katie payed 14.75
5) 91
Explanation: divide 18 by two and you get 9. When you add six and seven you carry on so those are your numbers. After you add you get your consecutive numbers, 91 and 92. 91 is the smallest so that is your answer
6)-18
Explanation: c+c+2=-34
2c+2-34
2x=-36
X=-18
18 is your answer
7) 17
Explanation: divide 22 is half. This is 11. 11+6=17. 17 is your answer
8)D
9)A
11-3 =x
However that isn’t an option so I would suggest to choose 3
10)D
4(17-n)=64
Step-by-step explanation:
"must be used first" is a very hard phrasing. multiplication is commutative.
and I am not sure that the problem is stated correctly.
I read here
(i×y²) to the power of 1/3.
i is the imaginary constant sqrt(-1) ?
exponents brought themselves to the power of something else multiply.
e.g.
![({2}^{3})^{4} = {2}^{12}](https://tex.z-dn.net/?f=%28%7B2%7D%5E%7B3%7D%29%5E%7B4%7D%20%20%3D%20%20%7B2%7D%5E%7B12%7D%20)
exponents in multimedia expressions of the same base simply add up.
e.g.
![{2}^{3} \times {2}^{4} = {2}^{7}](https://tex.z-dn.net/?f=%20%7B2%7D%5E%7B3%7D%20%20%5Ctimes%20%20%7B2%7D%5E%7B4%7D%20%20%3D%20%20%7B2%7D%5E%7B7%7D%20)
a negative exponent means that the expression with the same positive exponent is just at the bottom of a division.
e.g.
![{2}^{ - 3} = 1 \div {2}^{3}](https://tex.z-dn.net/?f=%20%7B2%7D%5E%7B%20-%203%7D%20%20%3D%201%20%5Cdiv%20%20%7B2%7D%5E%7B3%7D%20)
and a fraction as exponent specifies a root to be taken.
e.g
![{2}^{1 \div 3} = \sqrt[3]{2}](https://tex.z-dn.net/?f=%20%7B2%7D%5E%7B1%20%5Cdiv%203%7D%20%20%3D%20%20%5Csqrt%5B3%5D%7B2%7D%20)
so, I would do all the exponent multiplications to simplify the expression.
![\sqrt[3]{i \times {y}^{2} } = ({i \times {y}^{2} })^{1 \div 3} =](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bi%20%5Ctimes%20%20%7By%7D%5E%7B2%7D%20%7D%20%20%3D%20%20%28%7Bi%20%5Ctimes%20%20%7By%7D%5E%7B2%7D%20%7D%29%5E%7B1%20%5Cdiv%203%7D%20%20%3D%20)
![= ( { - 1}^{1 \div 2} \times {y}^{2} ) ^{1 \div 3}](https://tex.z-dn.net/?f=%20%3D%20%28%20%7B%20-%201%7D%5E%7B1%20%5Cdiv%202%7D%20%20%5Ctimes%20%20%7By%7D%5E%7B2%7D%20%29%20%5E%7B1%20%5Cdiv%203%7D%20)
1/2 × 1/3 = 1/6
2 × 1/3 = 2/3
![= { - 1}^{1 \div 6} \times {y}^{2 \div 3} = \sqrt[6]{ - 1} \times \sqrt[3]{ {y}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%7B%20-%201%7D%5E%7B1%20%5Cdiv%206%7D%20%20%5Ctimes%20%20%7By%7D%5E%7B2%20%5Cdiv%203%7D%20%20%3D%20%20%5Csqrt%5B6%5D%7B%20-%201%7D%20%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B%20%7By%7D%5E%7B2%7D%20%7D%20)
so, as we can see, we can move freely from multiplying the fraction exponents to converting them into root expressions and vice versa.
Answer:
x=42
Step-by-step explanation:
x-12=30
x=30+12
x=42
The answer is: (5w+8)(2w^2-3)
