A) h = 2sqrt2 because for a 45-45-90 triangle both legs have the same measurement and to find the hypotenuse, you would multiply the leg by square root of 2.

b) d = sqrt3 because in order to find the short leg for a 30-60-90 triangle, you would need to divide your long leg by a square root of 3 (if you have the hypotenuse and wanted to find the short leg, divide the hypotenuse by 2).

If you start with Malvin’s age, take half of it, increase that result by 5, then divide by 3, and finally double that, you get 8

Kisachek [45]

Answer:

24 years old

Step-by-step explanation:

Let Malvin's age be x.

x / 2
x / 2 + 5 = 5x / 10 [ By taking the L.C.M.]
( 5x / 10 ) * ( 1 / 3 ) = 5x / 30 [ Multiply with the reciprocal of 3 ]
( 5x / 30 ) * 2 = 5x / 15

Now let's solve the equation,

5x / 15 = 8

5x = 8 * 15

5x = 120

x = 120 / 5

x = 24

Therefore, Malvin is 24 years old.

It would be a + because the 7 in 7y is positive, therefore it would be added to the X’s. if it was -7y, then the underline would be a –.
