Answer:
≈ 83.9 cm²
Step-by-step explanation:
<u>Given:</u>
- P = a+b+c = 44 cm
- a = 18 cm
- b = 12 cm
<u>Then:</u>
- c= P -(a+b) = 44 -(18+12) = 14 cm
<u>Area of the triangle is found by using Herons formula:</u>
where s = P/2 = 44/2 = 22 cm
- A = √22(22-18)(22-12)(22-14) = √22*4*10*8= √7040 ≈ 83.9 cm²
Yes, because 20 is easy to multiple by 8. it ends in 0 and anything being multiplied by 2 is easy to find. 32 times 5 isn't exactly harder to figure out because its times 5 but its just not as easy to do right off the too of your head quickly.
Hey there!
14 + 3y < 65
SOME people replace “<”, “>”, “≥”, or “≤” as an equal sign (=) to make it easier to solve
14 + 3y < 65
14 + 3y = 65
SUBTRACT by 14 on both of your sides
3y + 14 - 14 = 65 - 14
CANCEL out: 14 - 14 because that gives you 0
KEEP: 65 - 14 because it helps you solve for “y”
**65 - 14 = 51**
NEW EQUATION: 3y = 51
DIVIDE by 3 both of your sides
3y/3 = 51/3
CANCEL out: 3/3 because that gives you 1
KEEP: 51/3 because it gives you the value of “y”
NEW EQUATION: y = 51/3
**51/3 = 17**
Answer: y = 17 ☑️
☑️ OVERALL ANSWER FOR YOU: y < 17 ☑️

Answer:
A
Step-by-step explanation:
You would first add c to the side that k is on and then divide k+c by 4 because it is 4x which means they are being multiplied together so you have to divide to get them apart.
I think it’s even because it can be divided by 2
