4(a + b) when a = 2 and b = 4

24

Step-by-step explanation:

a = 2, b = 4

4(a + b)

=> 4 (2 + 4)

=> 8 + 16

=> 24

24

Step-by-step explanation:

Use distributive property:

4(a + b) = 4a + 4b

Then substitute the values in for the variables:

4(2) + 4(4) = 8 + 16 = 24

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
