Suppose that a family wants to increase the size of the garden which is currently 16 feet long and 8 feet wide without changing

Cloud [144]

Answer:

See below

Step-by-step explanation:

Sides of the garden

16 feet and 8 feet

New dimensions of the garden

16 + 2x and 8 + x

1. The area of the new garden

(16 + 2x)(8 + x) =
2x^2 + 32x + 128

2. The difference in area

2x^2 + 32x + 128 - 16*8 =
2x^2 + 32x

3. x= 2 effect on the area

2*2^2 + 32*2 =
8 + 64 =
72 ft²

4. Area difference = 160

2x^2 + 32x = 160
x^2 + 16x - 80 = 0
Solving we get positive root of 4 ft

5. Area difference = 4 times

2x^2 + 32x = 128*3
2x^2 + 32x - 384 = 0
x^2 + 16x - 192= 0
Solving we get positive root of 8 ft

A bakery sold a total of 3028 coffee buns and blueberry buns. 1560 more coffee buns were sold than the blueberry buns. How many

Natali [406]

Answer:

$\large{ \tt{ - \: HEY \: AH~\:♡ }}$

$\large{ \tt{✺ \: SOLUTION}} :$

Provided : Total sold bakery items : 3028 coffee buns and blueberry buns & 1560 more coffee buns were sold than the blueberry buns.

To find : Number of coffee buns the bakery sold

- First , Subtract 1560 from 3028 :

$\large{ \tt{→ \: 3028 - 1560 = 1468}}$

We just subtacted the number of more coffee buns from the number of told items sold which means that the number of coffee buns and the number of blueberry buns sold are equal for now. Now divide 1428 by 2 :

$\large{ \tt{→ \frac{1428}{2} = 734 }}$

Now - Let's get back to the second sentence of the question and add 734 & 1560 :

$\large{ \tt{→ \: 734 + 1560 = \large{ \boxed{2294}}}}$

Hence , The bakery sold 2294 coffee buns.

- Hope this helps , oneesan! ;)
