Answer:

f(-3)

f(a) = -2a² - 5a + 4

Substitute a with its value, -3

f(-3) = -2(-3²) - 5(-3) + 4

f(-3) = -2(9) + 15 + 4

f(-3) = -18 + 19

f(-3) = 1

the value of f(-3) is 1.

A man is 32 years old and his son is 5 years old. How many years hence will the
ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

the current ages:

father= 32 yrs old

son=5 yrs old

-------

4(5+x) = 32+x

20+4x = 32+x

4x-x = 32–20

3x =12

x = 12/3

x = 4 years

------------------------------------

after the 4 years later the farther age will be 36 ( 32+4 = 36)

the son will be 9 ( 5+4= 9 years)

the x presents how the father will be after 4 times the age of the son
