Step-by-step explanation:

Let the painting's width be w inches and length be l inches.

w + 6 = 2l

w = 2l - 6 --(1)

2w + 2l = 84 --(2)

sub (1) into (2):

2(2l - 6) + 2l = 84

2l - 6 + l = 42

3l = 48

l = 16

when l = 16, w = 2(16) - 6 = 26

area of painting = lw = 16 x 26 = 416square inches

Therefore, only statements 1, 3 and 5 are true

What is the volume of the following rectangular prism?

blondinia [14]

Answer:

14/3

Step-by-step explanation:

To find the volume of a rectangular prism, you need to multiply the area of the base by the length or height of the prism. In this case, the area of the base is 3 1/3, and the length of the prism is 1 2/5 units. Multiplying these together you get:

$3\dfrac{1}{3}\cdot 1\dfrac{2}{5}=\dfrac{10}{3}\cdot \dfrac{7}{5}=\dfrac{70}{15}=\dfrac{14}{3}$ cubic units. Hope this helps!

What is the area of the composite figure whose vertices have the following coordinates?

Alex777 [14]

Answer:

Step-by-step explanation:

From the picture you can see that area is sume of area P1 and area P2.

a=6 because its egdes are on point -2 and 4, so it is 6. (See x-ose)

h=3 Edges on -2 and 1 (see y-ose)

k=2 edges on 3 and 1 on y-ose

P1=a*h=6*3=18

P2=a*k/2=6*2/2=6

P=18+6=24

mafiozo [28]

Answer:

Step-by-step explanation:

In the above problem it is given that

No of Bees in the hive = 14

Number of bees in the garden = 17

In order to solve it

First of all I wrote 14 in the first box which represents the number of bees in the hive.

Secondly, I wrote 17 in the second box which represents the number of bees in the garden.

Now, in order to calculate the total number of bees i added the number in both boxes

Total Number of bees = 14 + 17

Total Number of bees = 31

So our total number of bees are 31
