Answer:
Last Year Length = 4 meters
This Year Length = 12 meters
This Year Width = 10 meters
Step-by-step explanation:
We know, area of the rectangle is given by the formula:
Area = Length * Width
Given width = 5
Area = 20
We solve for Length:
Area = Length * Width
20 = Length * 5
Length = 20/5 = 4
Last Year Length = 4 meters
Now, this year, the length would be 3 times as long, so new length would be:
This Year Length = 4 * 3 = 12 meters
This year, the width would be two times previous year, so width would be:
This Year Width = 5 * 2 = 10 meters
Answer:
30 i think
Step-by-step explanation:
From what it looks like I don’t think it’s perpendicular because the points are not even from what it looks like I’m not the best in math
Answer:
Usually it's in standard form: ax²+bx+c
or vertex form: y=a(x-h)²+k
If you put the graph into a graphing calculator it's going to look like a hill/depression.
Step-by-step explanation:
Standard form ex: 3x²+2x+1
Vertex form ex: y=4(x-1)²-2
Answer: (x+10) to the seccond power
Step-by-step explanation: 1
Use the sum-product pattern
x^{2}+{\color{#c92786}{20x}}+100
x^{2}+{\color{#c92786}{10x}}+{\color{#c92786}{10x}}+100
2
Common factor from the two pairs
x^{2}+10x+10x+100
x(x+10)+10(x+10)
3
Rewrite in factored form
x(x+10)+10(x+10)
(x+10)(x+10)
4
Combine to a square
