Answer:A,C,E
Step-by-step explanation:
Answer:
A. 12
B. 26
Step-by-step explanation:
A. If the output is x = 3, then we just need to substitute 3 in place of x in the equation 2x + 6. This will give us a new equation, 2(3) + 6. 2 times 3 is 6, so we have 6 + 6 which is 12.
B. If the output is x = 10, then we just need to substitute 10 in place of x in the equation 2x + 6. This will give us a new equation, 2(10) + 6. 2 times 10 is 20, so we have 20 + 6 which is 26.

Answer:
Area: 28 square ft
Perimeter: 22 ft
Step-by-step explanation:
To find the area:
A=Lw
A is area, L is length, w is width
A=4*7
A=28
The area is 28 <em>square</em> feet
To find the perimeter:
P=2L+2w
P=2(7)+2(4)
P=14+8
P=22
The perimeter is 22 feet.
Hope this helps!
