Answer:

the answer is 84.56

Step-by-step explanation:

A = lw

A = 18 · 4

A = 72

The area of the rectangle is 72 cm2.

Circle

A = πr2

A = 3.14(2)2

A = 3.14(4)

A = 12.56

The area of the circle is 12.56 cm2.

Find the area of the bookmark.

A = 72 + 12.56

A = 84.56

What happens to the value of the expression 70 - 3g as g increases
exis [7]

Answer:

It decreases

Step-by-step explanation:

Given the expression: 70-3g

  • When g=1, 70-3g=70-3(1)=70-3=67
  • When g=2, 70-3g=70-3(2)=70-6=64
  • When g=3, 70-3g=70-3(3)=70-9=61
  • When g=4, 70-3g=70-3(4)=70-12=58
  • When g=5, 70-3g=70-3(5)=70-3=55

From the above, notice that as g increases, the value of the expression decreases.
