So first of all the question is asking you to convert feet to inches
If you would like to know the dimensions of the garden, you can calculate this using the following steps:
length ... (2 * x - 4) feet
width ... x feet
area ... 170 ft^2
area = length * width
170 = (2 * x - 4) * x
170 = 2 * x * x - 4 * x
170 = 2 * x^2 - 4 * x
0 = 2 * x^2 - 4 * x - 170 /2
0 = x^2 - 2 * x - 85
1. x = 1 - sqrt(86) = -8.27
2. x = 1 + sqrt(86) = 10.27
length: 2 * x - 4 = 2 * 10.27 - 4 = 16.54 feet
width: x = 10.27 feet
The dimensions of the garden are 16.54 feet and 10.27 feet.
-2/3a-6=12a
-6=12a+2/3a
-6=38/3a
3/38*-6=a
-18/38=a
a=-9/19
a=-0.47
Answer:
= 570
Step-by-step explanation:
Priority in order:
- Bracket
- X and /
- + and -
(50 x 40 / 4 + 20) + (50 / 2 + 25)
= (2000 / 4 + 20) + ( 25 + 25)
= ( 500 + 20) + ( 50 )
= ( 520 ) + 50
= 520 + 50
= 570
