answer
x=6,y=14
Step-by-step explanation:
make -5x+5x=40 as equation (1)
4x+3y=24...... (2)
Find equation (3) from (1)
-5x+5y=40
-5x/-5=(40-5y)-5
x= y-8............. (3)
Substitute (3) from (2)
4x+3y=24
4 (y-8)+3y=24
4y-32=24
4y=24+32
4y=56
y=14
find x from equation (3)
x=y-8
x=14-8
x=6
Answer:
D
Step-by-step explanation:

Answer:
1. 2 × 10⁵
2. 8 × 10⁴
3. 9 × 10⁸
4. 1 × 10¹⁰
Step-by-step explanation:
We can let the radius of the semi circles be r and x can be the length of the rectangle.
The perimeter will be Perimeter = 2x + 2pr = 1200
The area of the rectangle is Area = x(2r)
Once we solve the perimeter equation, you get x = 600.
Put this into the area equation and you get Area = (600 - pr)(2r)
The maximum then gives r = 95. 493 and area 57, 295.8
Dimensions
Height is twice the radius or 190.986. Find base use equation x = 600 - p(95.493) = 300.
This means dimensions are 300 by 190.986
