Answer:
<em>19</em>
Step-by-step explanation:
has a factor and
when divided by , remainder is 20.
To find:Remainder when divided by (x-1) ?
Solution:
is a factor
when we put this value of x to the function, it will become 0.
i.e.
Remainder is 20 when f(x) is divided by
i.e.
Solving (1) and (2), Multiply equation (1) by 2 and adding to (2):
By equation (1):
So, the equation becomes:
So, when divided by (x-1), remainder will be <em>19</em>.
Answer:
40
Step-by-step explanation:
Because these angles are the same, we can make an equation, 5x-5=3x+13.
2x - 18 = 2 • (x - 9)
Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : x-9 = 0
Add 9 to both sides of the equation :
x = 9
Replace x with 9 in this equation, 3(9) + 13
27+13
=40
Answer:
AC=12
Step-by-step explanation:
If vertices A and B lie on a diameter of the circle means that angle of triangle on the vertice C is 90, si this is right triangle. Now we can use Pitagora’s theorem to find AC.
AB^2=AC^2+BC^2
13^2=AC^2+5^2
169=AC^2+25
AC^2=169-25=144
AC=12
Answer:
It's 144 square units
Step-by-step explanation:
The pyramid has a square base with 8 sides and a slant height of 5
a=8
l=5
The total are of the square base pyramid is
A= +2al
a is side length of square and l is slant height
A= x 8 x 5
A=64+80
A=144
