Answer:
Y = 2x + 4
Explanation: if you subtract y from both sides you get -2x=4-y
Answer:
Option (3) is correct.
side length of square is (3x + 13 ) units.
Step-by-step explanation:
For a square with side 'a'. Perimeter is defined as the sum of length of side. Since, Square has four sides. Thus Perimeter of square = 4 × side
Given square has perimeter = 12x + 52
Comparing both sides,
4 × side = 12 x + 52
⇒ Side =
⇒ Side =
⇒ Side = 3x + 13
Thus, side length of square is (3x + 13 ) units.
Thus, option (3) is correct.
But I’m sure that I can do
<span>l ≤ 12
2l + 2w < 30
the second and fourth option are saying she can make the length longer than twelve and the third option forgets to double the length and width so it is accurate. The first option is the right answer.</span>
Answer:
A ≈ 55.6 cm²
Step-by-step explanation:
The area (A) of the shaded region is calculated as
A = area of circle × fraction of circle
central angle of shaded region = 360° - 230° = 130° , then
A = πr² ×
= π × 7² ×
= 3.14 × 49 ×
≈ 55.6 cm° ( to the nearest tenth )
