If the lcm of two numbers a and b is 40 what is the lcm of 7 a^2 and 7b^2
nekit [7.7K]

Answer:

11,200

Step-by-step explanation:

Given that the lcm of a and b  is 40 then a and b are factors of 40. All the multiples of 40 as sets are 1 and 40, 2 and 20, 4 and 10, 5 and 8. Of all these, only 5 and 8 would give a lcm of 40.

Let a = 5 and b = 8 as such,

7 a^2 = 7 * 5^2 = 175

7b^2 = 7 * 8^2 = 448

Then the lcm of 7 a^2 and 7b^2

= 11,200

Cameron is playing 9 holes of golf. He needs a total of at most 15 over par on the last four holes to beat his best golf score.
Svet_ta [14]

Cameron is successful at beating his record since he only shot 9 over par on the last 4 holes.

To find this, first turn each score into a number. Over pars are positive and under pars are negative. This gives us the following expression.

+5 - 1 + 6 - 1 = + 9

Therefore, he stayed below the + 15 that he needed.

How do I solve for X?
lidiya [134]
We use the theory of Pythagoras because the triangle is right.

AB {}^{2}  =  AC {}^{2}  +  BC {}^{2}
since AB = AC = x
8 {}^{2}  = x {}^{2}  + x {}^{2}
64 = 2x {}^{2}
32 = x {}^{2}
x =  \sqrt{32}
x =  \sqrt{16 }  \times  \sqrt{2}
x = 4 \sqrt{2}
