Step-by-step explanation:
there's no graph selection attached. Can you upload it and then I can help?
24 and 2/5=24+2/5
24=24
0.1=1/10
2/5=x/10
times both sides by 10
20/5=x
4=x
2/5=4/10=0.4
24 and 2/5=24+0.4=24.4
Answer:
7 3/25

Answer:
The rectangle is 3.2 cm by 12.6 cm
Step-by-step explanation:
See attached image for a diagram.
Choose <em>w</em> to represent the width because the length is described by referring to the width: it's 3 more than (add 3) triple (multiplied by 3) the width.
Length = 3w + 3
The diagonal forms two right triangles, each with leg = <em>w</em>, other leg = 3<em>w</em> + 3, hypotenuse = 13.
The Pythagorean Theorem says so
Now solve using the Quadratic Formula with .
The negative root makes no sense as a distance, so the width of the rectangle is 3.2 cm. The length is 3(3.2) + 3 = 12.6 cm.
I believe the answer would be -2 and -11 hope this helped!
