The formula for perimeter is 2L + 2W and the formula for the area is L * W, since we don't know the width we will divide 35:7 = 5 and he the measurement for the width.

Now just add L + W = 12 and multiply by 2 the answer is 24
Or 2 * 7 + 2 * 5 = 24

Kevin is 4 times as old as Daniel and is also 6 years older than Daniel.<br> How old is Kevin?
tester [92]

Answer:

kevin = 8 - hope this helped

:)

Step-by-step explanation:

Kevin = 4d  Kevin is 4 times as old as Daniel

Kevin = d + 6  Kevin is 6 years older than Daniel

4d = d + 6 They both equal K, so they are equal

3d = 6 subtracts D from both sides

d=6/3 = 2

If Daniel is 2 then Kevin is 4x2=8

If Daniel is 2 then Kevin is 2+6 = 8

Kevin is 8

Daniel is 2

For the following figure what’s the value of x?
Leto [7]

Answer:

x = 8 in

y = 8sqrt(2) in

Step-by-step explanation:

x = 8

AC = BC

Because opposite angles are equal.

8² + 8² = hyp²

hyp² = 64 + 64 = 128

hyp = sqrt(128)

hyp = 8sqrt(2)

Where sqrt is the square root

There are 26 third graders and 32 fourth graders going on a field trip. Each van can carry 10 students. How many cans are needed
iragen [17]

Answer:

26+32=10v

add numbers

58=10v

10v=58

divide both sides by 10

v=5.8

There will be 6 vans needed

58/6=9.6

There will be 10 students in four vans, and 9 students in two vans.
