Here's the expression based on your question:
2√7x + √7x - 3√7x - 7 =
3√7x - 3√7x - 7 =
0-7 =
-7
The correct answer is -7. You can easily subtract 2√7x, √7x, and 3√7x because they all have √7x in common, so it's basically the same as subtracting simple numbers 2, 1, and 3.
2*3*6 for large, 2*2*6 for med, 2*2*3 for small with 72 square cm as the surface area
Answer:
(0,-4), (2,6), and (4, 16) are solutions to this equation.
Yes the point (-5,-29) is a solutions
Step-by-step explanation:
(-5,-29) is a solution because if you plug in -5 for x, y will equal to the y in the ordered pair.
Combine like terms - in this case, that would be the real and imaginary parts:
(8 - 2i) + (5 + 9i) = (8 + 5) + (-2i + 9i)
… = 13 + 7i
Then <em>a</em> = 13 and <em>b</em> = 7.
Answer:
Concept: Numerical Analysis
- We want a number say X that represented as a percentage gives us 1,002.54
- Hence 539 × X = 1,002.54
- X = 1.86 %
