Answer:
x = -1 and x = 7
Step-by-step explanation:
2x^2 + 2x - 14x - 14
2x^2 - 12x -14
Divide through by 2 to simplify the expression
x^2 - 6x - 7
x^2 - 6x -7
Now, let's think of two numbers that when added up gives -6 and when multiplied gives -7
Yes! It's -7 and +1
-7 + 1 = -6 , and -7* 1 = -7
Now, lets substitute these numbers in the expression
x^2 -7x + x - 7
factorize
x(x - 7) + 1(x - 7)
(x + 1) (x - 7)
Now equate to zero
(x + 1) (x - 7) = 0
x + 1 = 0
subtract 1 from both sides
x +1 - 1 = 0 -1
x = -1
Also,
x - 7 = 0
Add 7 to both sides
x -7 + 7 = 0 + 7
x = 7
Hence, x = -1 and x =7
Answer:
32° + (x+9)° + (2x-8)° = 90°
32° + x + 9° + 2x - 8° = 90°
33° + 3x = 90°
3x = 90° - 33°
3x = 57°
x = 19°
angleCFD = 2×19 - 8
angle CFD = 30°
........
N,10,11,T
When you add 2 and 3 which makes 5 and the 5th letter in the alphabet is E
Then 6+8=N
10+11= U
Brainiest answer?
Answer:
Figure 3
Figure 1
Step-by-step explanation:
Figure 1 is the pre-image
The side length is 2. We multiply the side length by the scale factor.
2 * 4 = 8
The new figure will have a side length of 8. That will be Figure 3
Figure 2 is the pre-image
The side length is 4. We multiply the side length by the scale factor.
4 * 1/2 = 2
The new figure will have a side length of 2. That will be Figure 1
