First let’s divided 455 by 6.5 to figure out how far he travels in 1 hour which is equal to 70, now let’s do 2100 divided by 70, it will take 30 hours for him to drive 2100 miles.
Answer:
4x+9
Step-by-step explanation:
Perimeter=side+side
Therefore, 5+5+x+1+x+1+2x-3
so (10)+(2x+2)+(2x-3)
= 9+4x
Answer:
The perimeter is 16 yards.
_
Step-by-step explanation:
♤You can solve using the <u>pythagorean theorem</u>.
♡We will be using the variable 'x' to represent the variable 'b' in the picture provided.
◇In the pythagorean theorem, a and b represents bases while the c represents the hypotenuse (diagonal).

Answers are
a. 32 m
(2x6 + 2x10)
b. 45.2 cm
(4 x 11.3)
c. 23 in.
(6 + 7 + 10)
d. 34.6 cm
(2x 5.3 + 2 x 12)
e. 8 cm
(4 x 2)
f. 29 ft
(4 + 13 + 12)
Perimeter of each of these figures is found by adding the total of the sides.
