Step-by-step explanation:
Let's check
Circumference:-
➜2πr
➜<u>2πx</u>
New Circumference:-
➜2πr
➜2π3x
➜6πx
<u>Takin</u><u>g</u><u> </u><u>ratio</u><u>:</u><u>-</u>
➜2πx/6πx
➜1/3
➜1:3
<h3>Thus,</h3>
If we quadruple the radius Circumference will also be quadrupled.
Answer:
8
5x + 7 + ----------
x - 5
Step-by-step explanation:
Divide 5x 2 - 18x -27 by x - 5 using synthetic division. Important: Please use the symbol " ^ " to denote exponentiation.
Divide 5x^2 - 18x -27 by x - 5 using synthetic division.
Setting up synth. div., we choose the divisor to be 5. That comes from (x-5)=0. Then,
5 / 5 -18 -27
25 35
------------------------
5 7 8
Because the remainder (8) is not zero, x-5 is not a factor of 5x^2 - 18x -27.
The "answer" is thus:
8
5x + 7 + ----------
x - 5
Answer:
4
Step-by-step explanation:
5(2x-3)-(x+8) = 13
10x-15-x-8 = 13
9x = 36
x = 4
