Answer:
<h2>7.25</h2>
Step-by-step explanation:
I gave you the answer earlier too!
for more info !
<h2>there s a theorem called MIDPOINT THEOREM </h2>
Which means the 3rd side of the triangle is equal to 1/2 of the line drawn by joining the mid points
<h2>so AB=1/2of YZ</h2>
which means
2x-4 = 1/2×21
thus, 2(2x-4) =21
=> 4x-8 = 21
4x = 29
<h2>x= 29/4 = 7.25</h2>
3x + 2y = 4
2y = -3x + 4
Divide by 2
Solution: y = -3/2x + 2
x + 2y = -4
2y = -x - 4
Divide by 2
Solution: y = -1/2x - 2

Answer:
- 6.045×10^40 ergs
- 1.8×10^-2 mm
Step-by-step explanation:
A) Your scientific or graphing calculator can tell you the product:
(3.9×10^33 erg/s)(1.55×10^7 s) = 6.045×10^40 ergs
__
B) 10^2 mm is 100 mm, about 4 inches, so 1.8×10^2 mm is about 7 inches. This is somewhat larger than the diameter of a human hair (and about the same size as the diameter of a human <em>head</em>).
1.8×10^-2 mm = 18 μm is a more reasonable estimate of hair diameter
(The range of hair diameters is reportedly about 17 to 181 μm, so the given dimension is on the low end.)
The shortest side is 9, longest is 17 of the triangle IS NOT a 90 degree triangle
