Answer:

The length of a rectangle is 5 centimetres longer than twice its width. If the perimeter of the rectangle is 88 centimetres, what is the width?

width=x

length=2x+5

perimeter=88=2L+2W

 

so half perimeter=44=L+W

x+2x+5=44

3x=39

x=13 cm width ANSWER

2x+5=31 cm length

Step-by-step explanation:

given, length = 5cm

perimeter of a rectangle = 2(l+b)

88 = 2( l+ b)

88= 2( 5+ b)

88 = 10+ 2b

2b= 88-10

2b = 77

b= 77/2

b = 38.5

I think this is the answer

sorry if the answer is wrong and if I have done any mistake

1 and 2 are complementary. 1=x° 2=(3x 30)°
Sauron [17]
<span>3x + 2x = 90 {the two angles add up to 90°}
5x = 90 {combined like terms}
x = 18 {divided both sides by 5} 

angle 1 = 3x
= 3(18) {substituted 18, in for x, into 3x}
</span><span>= 54° </span><span>angles add up to 90° 

angle 1 = 3x
angle 2 = 2x

Use the list method to write "The perfect square integers between 1 and 80 inclusive".
oksian1 [2.3K]

ANSWER

{1, 4, 9, 16, 25, 36, 49, 64}

EXPLANATION

The perfect square integers between 1 and 80 inclusive are obtained by squaring the natural numbers from 1 to 8

{1}^{2}  = 1

{2}^{2}  = 4

{3}^{2}  = 9

{4}^{2}  = 16

{5}^{2}  = 25

{6}^{2}  = 36

{7}^{2}  = 49

{8}^{2}  = 64

The square of the next number does not fall within the given range.

Therefore "The perfect square integers between 1 and 80 inclusive" are

{1, 4, 9, 16, 25, 36, 49, 64}
