Answer:
Step-by-step explanation:
I think the one you want is the last one, but I've never called it that.
21x^2 + 147x + x^3 + 343
x^3 + 343 is a cubic binomial. It factors into (x + 7) (x^2 - 7x + 49)
21x(x + 7) + (x + 7)(x^2 - 7x + 49)
(x + 7) [ 21x - 7x + x^2 + 49)
(x + 7) [x^2 + 14x + 49]
(x + 7) ( x+7)^2
(x + 7)^3
It's the only answer that does factor. There must be a simpler way of doing it, but this will give you the right answer.
From (0, 0), the points A and D in the graph are at (-1, -1) and (2, -1) respectively.
<h3>How to depict the graph?</h3>
Since the scale factor is 2, every point will be moved twice a distance in both directions. (x and y).
So, multiplying both coordinates by 2, we will get the dilated points.
Hence, A' will be at (2 × (-1), 2 × (-1)) = (-2, -2) and D' will be at (2 × 2, 2 × (-1)) = (4, -2).

Answer:
The original number is 47.
Step-by-step explanation:
A and C when reversed make a number less than the original value.
D when reversed makes 83 which is 45 more than 38, the original number.
C, when reversed, gives 74 which is 24 more than 47, the original value.

Answer:
x=1
y=0
Step-by-step explanation:
x+3y = 1 equation 1
-5x+4y = -5 equation 2
using equation 1 we have:
x+3y = 1
x= 1-3y equation 3
using equation 3 in equation 2 we have:
-5(1-3y) +4y = -5
-5 + 15y +4y = -5
19y -5 = -5
19y = -5 +5
19y = 0
y=0
so we have:
x= 1-3y
x= 1- 3(0)
x=1
