Answer:
3a^2 + 20a + 34
Step-by-step explanation:
(2a + 5)^2 = 4a^2 + 20a + 25
(a +3)(a - 3) = a^2 - 9
Put these two partial answers together.
4a^2 + 20a + 25 -(a^2 -9 ) Remove the brackets.
4a^2 + 20a + 25 - a^2 + 9
4a^2 + 20a + 25 - a^2 + 9
3a^2 + 20a + 34
Answer:
x = -3
Step-by-step explanation:
to solve this equation you should first find the LCD or least common denominator for 2 and 6
the LCD is 6
so you should multiply each side by six
3x + 15 - x - 3 = 6
now combine like terms
2x + 12 = 6
now subtract both sides by 12
2x = -6
lastly divide everything by 2
x = -3
that is your answer
Answer:
Input:
sqrt(x^2 - 10 x + 25) = x - 5

Alternate forms:
sqrt((x - 5)^2) + 5 = x
sqrt((x - 5)^2) = x - 5
sqrt((x - 5)^2) - x = -5
Alternate form assuming x is positive:
x = abs(x - 5) + 5

Answer:
1. D
2. A
3. H
4. C
5. G
Step-by-step explanation:
Ok, so let's do this step by step, you'll only need to picture each panel/side individually, not the whole prism at once.
Start at point A, on both the prism and the flat layout.
On the layout, start with point A. You see that the #1 is along the long edge of A, on the same side... if you transpose that to the prism, you will arrive to vertex D. Do you see it?
Then from point 1 (D), we travel again on the long segment... to reach point #2, which is again point A.
For number 3, we see it's across the rectangle shape from F... if we look at that situation on the prism, we arrive at point H.
Point #4 is across point 1 (D) and diagonal to point 2 (A), so it's point C.
Point #5 is at the crossing of points C and F... so it's G based on the prism.
