Answer: 10:9

Step-by-step explanation:

brother 1- 1m 60cm

brother 2- 1m 44cm

_________________________________________________________

the ratio would be brother 1 : brother 2 => 1m 60cm : 1m 44cm

_________________________________________________________

convert both the values to cm

1m = 100cm

brother 1 would be 100cm + 60cm or 160cm

brother 2 would be 100cm + 44cm or 144cm

_________________________________________________________

$\frac{160}{144} = \frac{10}{9}$ when simplified

the ratio of brother 1 to brother 2 would be 10:9

The length of a rectangle is 6 inches more than its width. Its area is 91 square inches. The length is .

Vika [28.1K]

Answer:

13 in

Step-by-step explanation:

let w be width then length is w + 6

the area (A) of a rectangle is calculated as

A = length × width , then

A = w(w + 6) = 91 , that is

w² + 6w = 91 ( subtract 91 from both sides )

w² + 6w - 91 = 0 ← in standard quadratic form

(w + 13)(w - 7) = 0 ← in factored form

equate each factor to zero and solve for w

w + 13 = 0 ⇒ w = - 13

w - 7 = 0 ⇒ w = 7

however, w > 0 then w = 7

and length = w + 6 = 7 + 6 = 13 in
