Answer:

58 cm^2

Explanation:

there are three rectangles in the shape

the first one on the left has length = 7 cm and width = 3 cm.

so area = l × w

= 7×3

=21 cm^2

the one in the middle has length = 4 cm and width = (7- 3) => 4cm

so area = 4 × 4

= 16 cm^2

the last one to the right is identical to the first, so area = 21 cm^2

The combined area = 21 + 16 + 21

= 58 cm^2

Four - fifths of z added to six equals eight

ella [17]

The four-fifths of a number, in this case, z is four times the number divided by z. That is 4z/5. When we add six to the product and equate the expression to 8, we get,
4z/5 = 8
The value of z from the equation is 10.

Sheena baked 112 cookies she kept 16 cookies at home for her family and shared the rest evenly with her 8 friends how many cooki

sesenic [268]

Answer:

Each friend would get 12 cookies.

Step-by-step explanation:

Given:

Number of cookies she baked = 112 cookies

Number of cookies kept aside for family = 16

Number of friends she need to distribute cookies evenly = 8

We need to find number of cookies each friend would get;

Solution:

We will first find the number of cookies which needs to be distributed.

So we can say that;

number of cookies which needs to be distributed can be calculated by subtracting Number of cookies kept aside for family from Number of cookies she baked.

framing in equation form we get;

number of cookies which needs to be distributed = $112-16=96$

Now we will find number of cookies each friend would get.

number of cookies each friend would get can be calculated by dividing number of cookies which needs to be distributed from Number of friends she need to distribute cookies evenly.

framing in equation form we get;

number of cookies each friend = $\frac{96}{8}=12$

Hence Each friend would get 12 cookies.
