Answer: perimeter of the rectangle is 28 cm
54 cm and 30 cm
The new perimeter of the new rectangle is 168cm
The new perimeter is 6 times greater
Step-by-step explanation:
I just answered then and got it right
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:
1. true - dilating figures does not change their angle measure
2. true - dilating figures does not change the orientation, so AD would still be on a horizontal line parallel to its current position
No change. She gave the salesperson exactly the right amount to buy the racecar.
Let's try the actual solution of the system
<span>y = –2x + 1
y = –2x – 3
Note that the slopes of the graphs of these two lines are the same: -2.
That means that the lines are parallel to one another.
Only the y-intercepts (1 and -3) are different.
Since the 2 lines never intersect, the system has no solution.
