Answer:
( 4 x 10 y )
Step-by-step explanation:
You can't square root a negatove number so there isn't a root
(X-5)(2x+3)=x(2x+3)-5(2x+3)
=x*2x+3*x-5*2x-5*3
= 2x^2+3x-10x-15
=2x^2-7x-15
Terms are: 2x^2. ; -7x. ; -15
Answer:
C. 1 ≤ x ≤ 9 or x is between 1 and 9, inclusive
Step-by-step explanation:
I took this quiz before
Answer:
HCF = 14
LCM = 1680
Step-by-step explanation:
Factorizing the given values
210 = 2 * 3 * 5 * 7
112 = 2 * 2 * 2 * 2 * 7
Since 2 * 7 is common to both factors
Hence the HCF = 2 * 7 = 14
For LCM, we we will multiply all the prime factors that are in both
LCM = 2* 2 * 2 * 2 * 3 * 5 * 7
LCM = 112 * 15
LCM = 1680
Hence the LCM is 1680
