Answer:
(5x-1)^2=16
Step-by-step explanation:
<span>If you want to
convert 1.4 into a fraction, you can do it like this:
<span>
1 <span>equals to </span>1/1 <span>and </span>0.4 <span>equals to </span>4/10 <span>which simplifies to </span>2/5.
<span>The result is </span>1 2/5.
If you want to write the ratio of 1.4/7 in the simplest form, you can do this using the following steps:
1.4/7 = 1 2/5 / 7 = 7/5 / 7 = 7/5 * 1/7 = 1/5 = 0.2
The correct result would be 1/5.</span></span>
Let the width be X
Then the length is X + 70
The perimeter is the sum of all sides
There are 2 widths (left side and right side) and 2 lengths (top and bottom)
Perimeter = 2 * width + 2 * length
Perimeter = 2 * X + 2 * (X+70)
Perimeter: 2 X + 2 X + 140 = 380
4 X = 380-140
4 X = 240
X = 240 / 4
X = 60
Width = 60 - the smaller of two sides
Length = X + 70 = 60 + 70 = 130 - the larger of two sides
Check:
<span>
2 * 60 + 2 * 130 = 380 </span>
Answer:
the answer is c
Step-by-step explanation:
when looking at the graph you can see the intersection point which is (4,3) and at 4 months they were both 3 pounds. at the point of intersection they were the same age and same weight.
