Answer:

22.8

Step-by-step explanation:

the rectangular has :

the length CD =√[(3+3)²+(0-5)²]

= √(36+25) = √61 = 7.8

the width BC =√[(5-3)²+(3-0)²]

=√(4+9 =√13 = 3.6

so, the perimeter = 2(7.8 + 3.6)

= 2× 11.4 = 22.8

The sides of a rectangle are in the ratio 4:7. If its longer side is 31.5 in., find the shorter side, the perimeter, and the are
Lemur [1.5K]

Answer:

Width = 18 inches

Perimeter = 99 inches

Area = 567 square inches

Step-by-step explanation:

The sides of a rectangle are in the ratio 4:7. Then

Width =4x in

Length =7x in.

If  its longer side is 31.5 in, then

Length = 31.5 in

and

7x=31.5\\ \\x=\dfrac{31.5}{7}=4.5\ in

So,

Width =4\cdot 4.5=18\ in

The perimeter is

P=2(\text{Width}+\text{Length})\\ \\=2(18+31.5)\\ \\=2\cdot 49.5\\ \\=99\ in

The area is

A=\text{Width}\cdot \text{Length}\\ \\=18\cdot 31.5\\ \\=567\ in^2

Work out the values of a and b in the following identity
jeka57 [31]

Answer:

a = - 2 and b = - 3

Step-by-step explanation:

Distribute the parenthesis on the left side then compare like terms on both sides.

4(3x - 6) - 7(2x + b)

= 12x - 24 - 14x - 7b

= - 2x - 24 - 7b

Compare to right side ax - 3

For the 2 sides to be equal then

- 2x = ax ⇒ a = - 2

and

- 24 - 7b = - 3 ( add 24 to both sides )

- 7b = 21 ( divide both sides by - 7 )

b = - 3
