Answer:
3.54
Step-by-step explanation:
Well, we know it has to be 3.5 as our ones, and tenths place, (Thats what I did), and we know it can't be less than 3 for our hundredths place
If we do 0.05, or more as our hundredths place, than we won't be rounding right for the tenths place, so it has to be 3.54
2(4/3w+w) = 28”
(7/3w)=28”/2
3(7/3w) = 14”(3)
7w=42”
w=6"
Formula for perimeter is 2L + 2w = perimeter
2L + 2(6”) = 28”
2L = 28” - 12”
2L = 16”
L = 16”/2
L= 8”
Area = L(w)
Area = 8”(6”)
Area = 48 square inches
Answer:
The answer to your question is: first option
Step-by-step explanation:
Data
A (2, 5)
B (-2, -3)
Formula
Slope = m (y2 - y1)/(x2 - x1)
Line (y - y1) = m(x - x1)}
Process
m = (- 3 - 5) / (-2 - 2)
m = -8 / -4
m = 2
Substitution in line equation
(y + 3) = 2 (x + 2) Line equation
X is the number
30(x²)=8x
minus 8 both sides
30x²-8x=0
factor out 30x
30x(x-8/30)=0
set each to zero
30x=0
x=0, nope, we said x can't be 0
x-8/30=0
x=8/30
x=4/15
the number is 4/15
