Help me with 3 and 4 please! Explain how you got your answer, i will give out Brainliest

3-

area=1×(5-3) + (4-1)×5=2+15=17

4-

area=4×6+3.14×(4÷2)²/2=30.24

6-

area= 12×8-3×4=84

7-

area= 8×18+3.14×1²/2=147.45

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
