You can either round to 1000 or 2000 but 1.120 is closer to 1000
The equations that are true for x = -2 and x = 2 are (a) x^2 - 4 = 0 and (d) 4x^2 = 16
<h3>How to determine the true equations?</h3>
We have:
x = -2 and x = 2
Rewrite as:
x + 2 = 0 and x - 2 = 0
Multiply both equations
(x + 2)(x - 2) = 0
This gives
x^2 - 4 = 0 --- option (a)
Add 4 to both sides
x^2 = 4
Multiply by 4
4x^2 = 16 --- option (d)
Hence, the equations that are true for x = -2 and x = 2 are (a) x^2 - 4 = 0 and (d) 4x^2 = 16

Answer:
Step-by-step explanation:
Answer:no he will not finish the book in 1 week
Step-by-step explanation:
380 divided by 45 = 8.4
^^^means it take around 8 and 1/2 days to read finish the book
Step-by-step explanation:
y = 106° { being opposite angles of parallelogram }
12x - 9 = 10x + 7 ( being opposite sides of parallelogram)
12x - 10x = 7 + 9
2x = 16
x = 8
Hope it will help however the image wasn't clear i figured out by guessing .
