Answer:
C = 17.50n + 10
Step-by-step explanation:
You can plug the numbers into the equation 'y = mx + b' to get your answer.
Answer:
Area of living room
= 20(x+5)
= 20x +100
Area of dining room= 20x
Total area
= 20x +100 +20x
= 40x +100
Total perimeter (after wall is removed)
= 2(20) + 2( x+x+5)
= 40 + 2(2x+5)
= 40 +4x +10 (expand)
= 4x +50 (simplify)
Step-by-step explanation:
Area of rectangle= length × breadth
Titan: 135,000,000,000,000,000,000,000 kg
or 1.35 x 10^23 kg
Ariel: 1,350,000,000,000,000,000,000 kg
or 1.35 x 10^21
(the ^ symbol in between the numbers mean to make the number on the right side an exponent - hope it makes sense)
