Answer:
615.75
Step-by-step explanation:
A=4 times pi times r squared
4 times pi times 49 = 615.752160104
Round it to 615.75
D = 5x - 3y <=ANSWER
<span>8x + 4y - (3x + 7y) = 5x - 3y </span>
<span>13x + y - (8x + 4y) = 5x - 3y </span>
<span>18x - 2y - (13x + y) = 5x - 3y </span>
Answer:
A
Step-by-step explanation:
If we distribute the 3 to the equation in the parenthesis, we end up with this
12h + 6k
Now, let's do the same thing for the other two equations
3(2k + 4h) = 6k + 12h
You can rearrange this equation to look like 12h+ 6k, making it the exact same as 3(4h + 2k).
So A is equivalent
How about B?
3(4h + 2h) = 12h + 6h = 18h
18h does not equal 12h + 6k, so B is not equivalent
Answer:
10). 5x + (7x + 6) = 90
11). x = 7
Step-by-step explanation:
From the picture attached,
Sum of given angles measures 90°
Measures of the angles are (5x)° and (7x + 6)°
Therefore, equation to determine the values of x will be,
5x + (7x + 6) = 90
By combining similar terms of the equation,
12x + 6 = 90
12x = 90 - 6
12x = 84
x = 
x = 7
Therefore, by solving the equation value of x will be 7.
