2+2=4
3.54 times 2 is 7.08
3.5 times 3.5 is 7

17)
x² + 8 = -8
x² = -8 - 8
x² = 16
x = ±√-16
x = ±√16i
x = <span>±4i
</span>
18)
x² + 5 = -3
x² = -3 - 5
x² = -8
x = ±√-8
x = ±√8i
x = ±2√2i
19)
x² + 3 = 0
x² = -3
x = ±√-3
x = <span>±</span>√3i
hope this helps, God bless!
Answer:
It will be 3 in by 4 in
Step-by-step explanation:
Original dimension is 6 in by 8 in
If he scale it down by a factor of 1/2
The new dimension will be
1/2(6) by 1/2(8)
= 3 by 4
= 3 in by 4 in
You can't find the exact value of y, but you can find y in terms of x!
Adding 3y and subtracting 8 from both sides, we have:
2x-3y+3y-8=8+3y-8
2x-8=3y
Dividing by 3, we see that y=(2x-8)/3. This is the simplest form we can find for y.
