Do 10 to the sixth power first then multiply that by 7 you use PEMDAS
Answer:
hey
Step-by-step explanation:
7. X2=25
X=5, x=—5
8. (X—3)2=49
X=10, x=—4
9. X2+3x—28.
X=4, x=—7.
10. 5x2–8=3x.
X=8/5, x=—1
Part (A)
(1 cm)/(20 cm) = (6 cm)/(x cm)
1/20 = 6/x
1*x = 20*6
x = 120
120 cm = 120/100 = 1.2 m
<h3>Answer: 1.2 m</h3>
=========================================================
Part (B)
2.2 m = 2.2*100 = 220 cm
(1 cm)/(20 cm) = (x cm)/(220 cm)
1/20 = x/220
1*220 = 20*x
20x = 220
x = 220/20
x = 11
<h3>
Answer: 11 cm</h3>
Answer:
r=15.99
Step-by-step explanation:
