Answer:
A. 46.71
Step-by-step explanation:
I'm going to guess this is a "free-point" question, but here we go.
46.7 can be represented as 46.70, so, understandibly, adding 1 to the hundreths place gives you.
46.71
Hope this helps!
Answer:
Step-by-step explanation:
the distributive properrty of 6 + 30
6(1 + 5)
You can factor it more
Remember: (a^2 - b^2) = (a-b)(a+b)
(x^2 - 36) = (x - 6)(x + 6)
Now plug back to equation
(x - 6)(x + 6)(x + 7) = 0
x - 6 = 0, x = 6
x + 6 = 0, x = -6
x + 7 = 0, x = -7
Solution: x = 6, -6, -7
Answer:
240 = w (2w − 4) (w − 1)
Step-by-step explanation:
Volume of a rectangular prism is width times length times height.
V = wlh
Given:
V = 240
l = 2w − 4
h = w − 1
Substituting:
240 = w (2w − 4) (w − 1)
Answer:
Length: sqrt13 + 4
Width: sqrt13
Step-by-step explanation:
Denote the width as x, then the length is x+4. The area of the rectangle will be x(x+4), and the perimeter will then be 4x +8. Hence, you can write the equation x(x+4) - 5 = 4x+8. Solving, you get x = sqrt13.
