Answer: 11
Step-by-step explanation:
11+1=12
4(11-8)=
4(3)=12
Answer:
The equation is;
(2x-2) + (4x + 2) = 180
x = 30
m∠A = 58
Step-by-step explanation:
Mathematically, when two angles are supplementary, the values of both angles add up to be 180
From
what we have here;
(2x -2) + (4x + 2) = 180
2x -2 + 4x + 2 = 180
6x = 180
x = 180/6
x = 30
Recall;
The measure of angle A is as follows;
2x -2 = 2(30) - 2 = 60-2 = 58
Answer:
There are 3 critical values of f on the open interval (0,10).
Step-by-step explanation:
It is given that the first derivative of the function f is
We need to find the number of critical values of f on the open interval (0,10).
To find the critical values we have to find the value of x for which f'(x)=0.
Using graphing calculator we get
All the values 1.086, 2.320, 3.681 lie on the interval (0,10).
Therefore, there are 3 critical values of f on the open interval (0,10).
Using a/sinA=c/sinC
a=24 c=38
A=39
24/sin39=38/sinC
SinC=38sin39/24
I don’t have a calculator now but that’s the answer
Answer:
Step-by-step explanation:
(a). = x ( 2x + 1 ) = <em>2x² + x</em>
(b). = 2( 2x + 1 )( 5x + 3 ) = <em>20x² + 22x + 6</em>
(c). = 20x² + 22x + 6 - ( 2x² + x ) =
( 20x² - 2x² ) + ( 22x - x ) + 6 =
<em>18x² + 21x + 6</em>
