Question 1: c. ) 8^4 question 2: 4^7 question 3: 7^6 question 4: 4^3 question 5: 3^2
Answer: 8+18W
Step-by-step explanation:
1. First multiply the 4 by 2, equalling 8.
2. Then multiply the 9W by 2, equalling 18W.
3. 8 and 18W are unlike terms, so they can not be added together.
4. The answer would stay as 8+18W.
Answer: The dimensions of the rectangle are 6ft and 16ft.
Step-by-step explanation:
Let the width of the rectangle be y
Let the length of the rectangle be y+10
Area= 96ft
Since area of a rectangle is length multiplied by width
y(y+10) = 96
y^2 +10y =96
y^2 +10y -96= 0
Solving algebraically,
y^2 +16y - 6y - 96= 0
y(y+16) - 6(y+16)= 0
(y-6)(y+16)= 0
y-6= 0
y =6ft
Recall that the width was denoted as y. That means the width is 6ft.
Since length is y+10= 6+10 = 16ft
Length is 16ft, width is 6ft.
