Answer:
12 ft²
50 ft²
Step-by-step explanation:
∆ABD = ∆CBD
Perimeter of ∆ABD = 12 ft²
Perimeter of triangle ∆CBD
If ∆ABD = ∆CBD
Then, Perimeter of ∆CBD = 12 ft²
∆ABC = ∆CDA
Area of ∆ABC = 25 ft²
Then the area of rectangle ABCD = Area of ∆ABC + Area of ∆CDA
= 25 ft² + 25 ft²
= 50 ft²
Answer:

[12,∞]
Step-by-step explanation:
Hi There!
Follow y = mx + b
m = slope
b = y intercept
(a) What are the slope and the y-intercept for the equation that represents the number of baskets of berries the workers picked over a period of time?
Slope = 5
Y intercept = 10
(b) What are the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount for the situation.
The rate of change is how much it takes for the amoun to change. The initial amount should be going up with a slope of 5 each time.
(c) Use graph paper to draw a graph representing the situation. Label the axes appropriately.
Start at the origin than continue with a slope of 5 and make sure the y intercept is correctly graphed.
Answer:
(5 , 0)
Step-by-step explanation:
7 * (−9y+4x−20)=0
9 * (−7y+16x−80)=0
-63y + 28x -140 = 0 ......a
-63y + 144x -720 = 0 .....b
b-a: 116x - 580 = 0
116x = 580
x = 5
y = (4x-20)/-9 = 0/-9 = 0
3+8=11
11 units
99=11 units
divide by 11 both sides
9=1 unit
plums=8 units
8*9=72
72 plums
