Answer:
Area of remaining cardboard is 224y^2 cm^2
a + b = 226
Step-by-step explanation:
The complete and correct question is;
A rectangular piece of cardboard is 16y cm long and 23y cm wide. Four square pieces of cardboard whose sides are 6y cm each are cut away from the corners. Find the area of the remaining cardboard. Express your answer in terms of y. If your answer is ay^b, then what is a+b?
Solution;
Mathematically, at any point in time
Area of the cardboard is length * width
Here, area of the total cardboard is 16y * 23y = 368y^2 cm^2
Area of the cuts;
= 4 * (6y)^2 = 4 * 36y^2 = 144y^2
The area of the remaining cardboard will be :
368y^2-144y^2
= 224y^2
Compare this with;
ay^b
a = 224, and b = 2
a + b = 224 + 2 = 226
Answer:
independent: time (hours)
dependent: distance (miles)
Step-by-step explanation:
The independent variable would be time because it can be changed depending on his walking speed.
The dependent variable would be distance
Answer:
R300
Step-by-step explanation:
<u>To solve:</u>
- Multiply 25 by 6 to represent the earnings of a shift.
- Multiply the shift earnings by 2 to represent how much he earned over the weekend.
