Step-by-step explanation:
The applicable property of exponents is ...
![\sqrt[n]{x^m}=x^{\frac{m}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Em%7D%3Dx%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D)
The 4th selection uses this property directly. The 3rd selection uses the property
to show that the cubes of the two expressions are equivalent. Since all the numbers involved are real numbers, this is equivalent to showing the expressions equivalent.
Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
4x + 3y = 1 → (1)
x - 3y = - 11 → (2)
Adding the 2 equations term by term will eliminate the y- term
5x + 0 = - 10
5x = - 10 ( divide both sides by 5 )
x = - 2
Substitute x = - 2 into either of the 2 equations and solve for y
Substituting into (1)
4(- 2) + 3y = 1
- 8 + 3y = 1 ( add 8 to both sides )
3y = 9 ( divide both sides by 3 )
y = 3
solution is (2, - 3 )
First, multiply 3.5 by 20 and 2 by 20 to get the real width and length of the room(That would be 70 in. long and 40 in. wide). Then, change that into feet (Which would be 5.8 ft. long and 3.3 ft. wide). Lastly multiply the length by the width. The answer would then be 19.14.
Answer:
24m²
Step-by-step explanation:
To find the area of a rectangle, we use the formula A = l * w or Area = length * width.
We know that our length is 2 meters and our width is 12 meters so we can plug these values into the formula to get our answer.
A = 2 * 12 = 24
Remember that area is measured in "square" units and must be raised to the 2nd power.
A = 24m²
