Question

Evaluate each expression if a = 6 and b = 14.1) 3a – b2) b + 253) 4a + 54) 2b + 6a

Answer 1

Recall that to evaluate an expression we substitute each variable by the given corresponding value. Therefore:

1)

`3\cdot6-14=18-14=4.`

2)

`14+25=39.`

3)

`4\cdot6+5=24+5=29.`

4)

`2\cdot14+6\cdot6=28+36=64.`

Answer:

(1) 4.

(2) 39.

(3) 29.

(4) 64.
