Answer:
324
Step-by-step explanation:
L = 4W
P = 2L + 2W = 90
---
2L + 2W = 90
2(4W) + 2W = 90
8W + 2W = 90
10W = 90
---
W = 9
L = 36
---
A = 324

Step-by-step explanation & answer:
When a dilation in the coordinate plane has the origin as the center of dilation, we can find points on the dilated image by multiplying the x and y coordinates of the original figure by the scale factor.
For example, if the scale factor is "k", the algebraic representation of the dilation is
(x, y) → (kx, ky)
For enlargements, k > 1 and for reductions, k < 1.
Hope this is what you needed:)
Answer:
y=2/5x+3/5
Step-by-step explanation:
Use the slope formula to get the slope:
m=4/10
m=2/5
The y intercept is 3/5
The equation is y=2/5x+3/5
Answer:
The required equation of line in point-slope form is:

Step-by-step explanation:
Given points are:
(x1,y1) = (3,6)
(x2,y2) = (5,-8)
The point-slope form of an equation is given by:

Here m is slope of the line and (x1,y1) is a point on line
The slope is calculated using the formula:

Putting the values we get

Putting in the equation

Now we have to put a point in the equation, putting (3,6) in the equation

Hence,
The required equation of line in point-slope form is:

Answer:
1/5 divided by 4 equals to 0.05
