Answer:
20
Step-by-step explanation:
if you multiple 5 by 4 you will get 20 so the final answer is 20
Answer:
y = 1/2x + 2
Explanation:
The line intercepts the y-axis at 2, so that would be "b" using the slope-intercept formula y = mx + b. (I won't explain the slope as I am tired now.)
Note that both 5 and 4 are exponents, and their product is 5*4=20, or 4*5=20. Thus,
(3^5)^4 is equal to (3^4)^5
Review:
(a to the power b)to the power c = a to the power bc.
Thus, (3 to the power 5)^4 = 3^20; the same is true if you reverse the positions of the 5 and the 4.
√x+7
√9+7
the square root of 9 is 3 (because 3*3=9)
3+7
10
Answer=10
Answer:
Given,
Area of the Square = ( x² - 10x + 25 ) m²
We have to find: Length of the side of the square.
Let s be the side of square.
We find length of side of the by using factorization.
According to the question,
s² = x² - 10x + 25
s² = x² - 5x - 5x + 25
s² = x( x - 5 ) - 5( x - 5 )
s² = ( x - 5 )( x - 5 )
s² = ( x - 5 )²
Taking square root on both sides we get,
s = x - 5
Therefore, Expression that represents the length of one side of the square is x - 5.
