Hello
Select the expression represented by the tiles. Remember, red tiles represent negative
quantities.
A. xsquared + 3x – 4
B. xsquared + 7x - 4
C. – xsquared-7x -4.
D. - xsquared + 3x -4
x^2 + 5x - 2x - 4
= x^2 + 3x - 4
Answer A)
The expression that is equal to (x Superscript one-fourth Baseline y Superscript 16 Baseline) is x Superscript one-eighth Baseline y Superscript 8.
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The expression that is equal to (x Superscript one-fourth Baseline y Superscript 16 Baseline) can be found by simplifying the given algebraic equation,
![(x^{\frac14}y^{16})^{\frac12}\\\\=x^{(\frac14 \times \frac12)} \times y^{(16 \times \frac12)}\\\\= x^{\frac18}y^{8}](https://tex.z-dn.net/?f=%28x%5E%7B%5Cfrac14%7Dy%5E%7B16%7D%29%5E%7B%5Cfrac12%7D%5C%5C%5C%5C%3Dx%5E%7B%28%5Cfrac14%20%5Ctimes%20%5Cfrac12%29%7D%20%5Ctimes%20y%5E%7B%2816%20%5Ctimes%20%5Cfrac12%29%7D%5C%5C%5C%5C%3D%20x%5E%7B%5Cfrac18%7Dy%5E%7B8%7D)
Hence, the expression that is equal to (x Superscript one-fourth Baseline y Superscript 16 Baseline) is x Superscript one-eighth Baseline y Superscript 8.

Hello from MrBillDoesMath!
Answer: NO points of intersection. The two lines are parallel
Discussion:
Rewrite the equations so the variables and constants line up vertically
x - 2y + 8 = 0
x - 2y -6 = 0 (I added "x" to both sides of the second equation)
Subtract the bottom equation from the the top one:
(x - 2y + 8) - ( x - 2y -6) = 0 or
x - 2y + 8 - x + 2y + 6 = 0 or
(x-x) + (-2y +2y) + (8 + 6) = 0 or
0 + 0 + 14 = 0
14 = 0 !
No solution exists. (Another approach: What is the slope of each line? Hint: 1/2. Since the slopes are the same the lines are parallel and have no points of intersection)
Thank you,
MrB
Answer:
theyre correct
Step-by-step explanation:
Hello!
1 ft = 12 inches.
10.5 ft = 126 inches.
11.5 × 2.3 = 26.45
126/26.45 = 4.76 (About)
4.76 large doors can be cut from a 10.5 ft long board.
