What ! does this make any sense
Answer:
1. 14.5
2. 16
Step-by-step explanation:
1. a^2 + b^2 =c^2
20^2 + 21^2 = c^2
400 + 441 = c^2
841 = c^2
= ![\sqrt{c}](https://tex.z-dn.net/?f=%5Csqrt%7Bc%7D)
29 = c
29/2 = x
14.5 =x
2. c^2-b^2 = a^2
34^2 - 30^2 = a^2
1156 - 900 = a^2
256 = a^2
= ![\sqrt{a}](https://tex.z-dn.net/?f=%5Csqrt%7Ba%7D)
16 = a
Answer:
18. Its 2 meters.
19. Its 0.2 grams
20. Its 1,920
Step-by-step explanation:
When you convert 200 centimeters to meters its 2.
When you convert 2,000 milligrams in grams its 0.2
15% of 12, 800 is 1,920

<em>Answer:</em>
<em>Step-by-step explanation:</em>
<h2><u><em>
21u²</em></u></h2>
The formula for the area of a parallelogram is base times height
so
x = 7 (base)
y = 5
h = 3 (height)
7 * 3 =
21u²
Not sure what choices you are given but
3+4x=51
-3 -3
4x=48
divide by 4 to both sides
x=12
