Answer and explanation:
- 5 = b - 2.3 add 2.3 to both sides
+2.3 +2.3
- 2.7 = b
Oof, division rule:
(f/g)'=(f'g-fg')/g^2
Let (9t-8)^6=f and t+2=g
Thus we get
(9*6(9t-8)^5*(x+2)-(9t-8)^6)/(x+2)^2
(54(9t-8)^5*(x+2)-(9t-8)^6)/(x^2+4x+4)
I'm not sure how much I'm supposed to simplify this...
Answer:
Step-by-step explanation:
Let the width of the rectangle = x
As length is 5 inches longer than width, we have to add 5 to width
Length = x + 5
Perimeter of ractangle = 56 in
2* (length + width) = 56
2*( x + 5 + x) = 56
2* (2x + 5) = 56
Use distributive property: a*(b +c) =(a*b) + (a * c)
2*2x + 2*5 = 56
4x + 10 = 56
Subtract 10 from both sides
4x = 56- 10
4x = 46
Divide both sides by 4
x = 46/4
x = 11.5
Width = 11.5 in
length = 11.5 + 5
= 16.5 in
