Answer:
x = 72
Step-by-step explanation:
These angles are complementary so they add up to 90:
x + 18 = 90
x = 90 - 18
x = 72
Answer:
Factors (2 x 2 x 3 x 3 x 5 x 5 = 900). It can also be written in exponential form as 22 x 32 x 52.
Step-by-step explanation:
Answer:
364.
Step-by-step explanation:
14C3 = 14! / 11! 3! which simplifies to:
14*13*12 /3*2*1
= 14*13* 2
= 364.
Answer:
Step-by-step explanation:

Let us divide by 14 by 7 which is 2, so the equation is:

Let us multiple 21 over the other side since 21 is in the denominator of the equation, so we get

So the answer is 42.
Answer:
34 = 2 × 17
Step-by-step explanation:
To reduce a fraction divide the numerator and the denominator by their greatest common factor, GCF
