Answer:
Step-by-step explanation:
To find the HCF of 144 and 180
By using product of prime method
Firstly express 144 as a product of it prime and express 180 as a product of it prime
140=2×2×2×2×3×3
180=2×2×3×3×5
Common factor =2×2×3×3
36
in term of m
m=36
13m-3
To find m
Substitute for m when m=36
13(36)-3=
465
Area=legnth times width=31
the frame must go around the frame with equal legnth, x
so
the total area (meaning the frame +picture) is 5+x by 6+x
31=(5+x)(6+x)
expand
31=30+11x+x^2
minus 31 both sides
0=-1+11x+x^2
x^2+11x-1=0
answer is third one
Answer:
50y^4x/49
Step-by-step explanation:
y^3/98
((100* y^3/98 * x) * y
2.1 y^3 * y^1=y^(3+1)=y^4
Answer:
the youngest brother is of 2 years and 5 months
if this rule still applies, the next son will be born in 2 months.
Step-by-step explanation:
Given that:
Oldest son= 11 3/4 years old = 11 years 3/4 (12) months = 11 years 9 months
Difference = 2 years 7/12(12) months = 2 years 7 moths
So for finding the age of youngest brother:
Subtract the difference others from age of oldest:
= 11 years 9 months - 4(2 years 7 months)
= 11 years 9 months - 9 years 4 months
= 2 years 5 months
So the youngest brother is of 2 years and 5 months
if this rule still applies, the next son will be born in 2 months.
i hope it will help you!
