Answer:
(1,2)
Step-by-step explanation:
The solution to the system is where the two lines cross.
They cross at x=1 and y=2
(1,2)
Answer: 256 feet
Step-by-step explanation:
Base Surface Area = 162
= 256 feet2
Lateral Surface Area =
2×16× √
( 16 )2 + 202
2
= 689.30109531322 feet2
Total Surface Area = 945.30109531322 feet2
Answer:
6
Step-by-step explanation:
11 = 11*1
8 = 2*4
They have no common factors, so the LCM (least common multiple) is
2*4*11 = 88
The multiples of 8 and 11 below 600 are multiples of 88
88*1 =88
88*2 =176
88*3 =264
88*4 =352
88*5 =440
88*6 =528
This is the last multiple because if we add 88 if would be over 600
I believe the answer is B because you distribute 4(x-8) to get 4x-32 and distribute 7(x-4) to get 7x-28
Solution:
The difference of cubes identity is
if a and b are any two real numbers, then difference of their cubes , when taken individually:
→a³ - b³= (a-b)(a² + a b + b²)→→→Option (D) is true option.
I will show you , how this identity is valid.
Taking R H S
(a-b)(a² +b²+ab)
= a (a² +b²+ab)-b(a² +b²+ab)
= a³ + a b² +a²b -b a² -b³ -ab²
Cancelling like terms , we get
= a³ - b³
= L H S
