remove the ( ) fast and then add the numbers that look the same.
(22+19b)+7
22+19b+7
22+7+19b
= 29+19b

18+(5+6m)
18+5+6m
= 23+6m

here u don't care about same or not same u just multiply or divide
11s(4)
= 44s

10y(7)
= 70y

(9+31+5)(7times5)times4)
(45)(35)4
(1575)4
= 6300

Help with#14 please!!!

Alisiya [41]

<h3> $▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$ </h3><h3 /><h3><u>Question</u> : 14</h3>

let's solve for f :

$\dfrac{1}{f} = \dfrac{1}{a} + \dfrac{1}{b}$

$\dfrac{1}{f} = \dfrac{b + a}{ab}$

Taking reciprocal of both sides :

$f = \dfrac{ab}{a + b}$

A square 20 cm long and a rectangle 24 cm long have the same perimeter. Find the area of the rectangle.

Nitella [24]

20 * 4 = 80 = perimeter of the square 24*2 = 48, the length of two sides of the rectangle. Deducting from 80 we are left with 32 and dividing by 2 we know the rectangle is 24 x 16 Area = L * W, so you can calculate the area of the rectangle.
