Step one -simplify both sides of the equation
-5/8c=20
step two-multiply both sides by 8/(-5)
(8/-5)*(-5/8c)=(8/-5)*20
answer:
c=-32
Answer:
(200π - 12)ft
or
616.32 ft
Step-by-step explanation:
Given in the question,
there are four circle around which corn will be planted.
radius of first circle = 10 ft
radius of second circle = 20 ft
radius of third circle = 30 ft
radius of fourth circle = 40ft
circumference = 2πr
First circle
2π(10)-3
20π -3
Second circle
2π(20)-3
40π-3
Third circle
2π(30)-3
60π-3
Fourth circle
2π(40)-3
80π-3
Add them up
80π - 3 + 60π - 3 + 40π - 3 + 20π - 3
(200π - 12)ft
or
616.32 ft
Answer:
When we are trying to square a number say x, to x²,then we multiply the number x with number of powers
here since it is x² we multiply x × x
if it is x³,then x × x × x
Answer:
3(4x - 1)(2x + 3)
Step-by-step explanation:
Rearrange the equation into standard form
Subtract 9 - 30x from both sides
24x² + 30x - 9 = 0 ← in standard form
Take out 3 as a common factor
3(8x² + 10x - 3) = 0 ← factor the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x term
product = 8 × - 3 = - 24, sum = 10
The factors are - 2 and + 12
Use these factors to replace the x- term, that is
8x² - 2x + 12x - 3 ( factor the first/second and third/fourth terms )
2x(4x - 1) + 3(4x - 1) ← take out the common factor (4x - 1)
(4x - 1)(2x + 3)
24x² + 30x - 9 = 3(4x - 1)(2x + 3) ← in factored form
Answer: 28.8°
<u>Step-by-step explanation:</u>
∠A = 5(∠B) + 7.2°
∠B = ∠B
Since they are on a straight line, they form a linear pair (sum = 180°)
∠A + ∠B = 180°
Use Substitution:
5(∠B) + 7.2° + ∠B = 180°
Add like terms:
6(∠B) + 7.2° = 180°
Subtract 7.2° from both sides:
6(∠B) = 172.8°
Divide both sides by 6:
∠B = 28.8°
