Answer:
Length: 5 ft; width: 4 ft.
Step-by-step explanation:
A = LW formula for area of rectangle
(2x + 1)(2x) = 20 substitute length, width, and area into formula
4x² + 2x - 20 = 0 use the distributive property to multiply out left side
2x² + x - 10 = 0 divide both sides of equation by 2
(2x + 5)(x - 2) = 0 factor out trinomial
2x + 5 = 0 or x - 2 = 0 use zero product rule to solve for x
2x = -5 or x = 2 subtract 5 from both sides; add 2 to both sides
x = -5/2 or x = 2
We discard x = -5/2 since it would give negative length and width, and the length and width cannot be negative.
Length: 2x + 1 = 2(2) + 1 = 5
Width: 2x = 2(2) = 4
Length: 5 ft; width: 4 ft.
Answer:
10 because 5+7 is 12 12 is closer to 10 then 15
so ten. below is your reason
Step-by-step explanation:
If i add 5+7 that will give me 12 i know that when you round you always round to the nearest tenth so i know that 12 is closer to 10 then 15 so my answer will be ten
can i please have brainliest please
have a great day!! :)
The base should be 4.
Area=1/2* b *h
4*7=28/2=14.
