Answer:
Step-by-step explanation:
Replace the variables with the number it is so
5. 3 • 8 - 8 = 16
6. 6 • 1/2 divide by 3 + 9 = 10
7. 8 to the power of 2-12• 1/2 divided by 3 = 62
8. 5 • 3-2 • 3 + 8= 17
9. 824/ 4 = 206
10. 6• 60/ 9 - 22 = 18
11. 16.8/2.4 = 7
12. 9.85 • 4 = 39.5
(“•” mean multiply)

Rope = 225 cm
Needed rope = 11/2m = (11/2) × 100 cm = 550cm
So, rope needed to be cut
= 550cm - 225cm
= 225cm
=225/100m
=2.25 m
Answer:
1: x = -1
2: x = 3
3: x = -3
Step-by-step explanation:
f(x)=<u>x^3+x^2</u>−9x−9
f(x)=x^2<u>(</u>x+1) <u>−9x−9</u>
f(x) = x^2<u>(x+1)</u> - 9<u>(x+1)</u>
f(x)= (x+1)<u>(x^2-9)</u>
f(x) =(x+1)(x-3)(x+3)
