Remember, the exact value cannot involve any rounding or estimates. Now, let's solve this problem. First, we have to translate it into an expression:
√72 - √8 + √128 separate the terms into square roots
√36·2 - √4·2 + √64·2 square root the terms that you can
6√2 - 2√2 + 8√2 they have like radical terms, so combine the terms
6 - 2 + 8 = 12 the coefficients are 12 when combined
12√2 this is the EXACT VALUE of the expression
Hope this helps!
Answer:
![4 \sqrt[3]{6x}^{2}](https://tex.z-dn.net/?f=4%20%5Csqrt%5B3%5D%7B6x%7D%5E%7B2%7D)
Step-by-step explanation:
a like radical just means one that's similar to the original. going through your options, you should look for one with the exact same contents in the brackets as the one asked in the question. in this case, we see it's the third one because the contents inside are the same. the outside value (or known as the stretch/compression value) doesn't change the fact that it is still like to the original.
Answer:
x=-7
Step-by-step explanation:
5x-2x+1=3x-6-x first combine like terms
3x+1=2x-6 combine like terms by subtracting 2x from both sides
x+1=-6 subtract 1 from both sides
x=-7
Answer:
Step-by-step explanation:
m∠EBC = 45°
3x + 9y = 45
Divide the entire equation by 3
x + 3y = 15 --------------------(I)
m∠EAB = 45
5x + 5y = 45
Divide the entire equation by 5
x +y = 9 -------------(II)
Multiply equation (II) by (-1)
(I) x + 3y = 15
(II)*(-1) <u> - x - y = -9</u> {Now add}
2y = 6
y = 6/2
y = 3
Plugin y = 3 in equation (I)
x + 3*3 = 15
x + 9 = 15
x = 15 - 9
x = 6
