the square root of a number is: one number times itself equals that number. Confusing '-' An example is the square of 4 is 2 because 2 times 2 = 4, or the square root of 56 is 8 because 8 times 8 is 64. The square root of 175 is about 13.22875 because 13.22875 times 13.22875 = about 175
Answers:
2x - 6y = 8 -> x = 4 + 3y
-3x + 9y = 12 -> x = -4 + 3y
Answer:
the sum is 360 degrees, which means
360 = 124 + 124 + 2x + 2x
360 = 248 + 4x
-4x = 248 - 360
-4x = -112
x = 28
Check:
124 + 124 + 2(28) + 2(28) =
360
Your answer is x = 28
let me know if you have any questions <3
Answer:
length is 26 and width is 23
Step-by-step explanation:
let width be x
then length is 3+x since it is 3 more than the width
perimeter of a rectangle = 2l + 2w
98=2 [3+x] + 2x
98=6+2x+2x
98=6+4x
98-6=4x
92=4x
x=23
width is 23 and
breadth is 26
Answer:
D
Step-by-step explanation:
The expression ![\sqrt[5]{x} *\sqrt[5]{x}* \sqrt[5]{x} *\sqrt[5]{x}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%7D%20%2A%5Csqrt%5B5%5D%7Bx%7D%2A%20%5Csqrt%5B5%5D%7Bx%7D%20%2A%5Csqrt%5B5%5D%7Bx%7D)
simplifies to ![\sqrt[5]{x*x*x*x} = \sqrt[5]{x^4}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%2Ax%2Ax%2Ax%7D%20%3D%20%5Csqrt%5B5%5D%7Bx%5E4%7D)
A radical can be written as a fractional exponent. The index of a radical is the denominator of its fractional exponent.
