Answer 1

Answer:

120

Step-by-step explanation:

Given

u = 14 , a = 8 , t = 4

Now, let's find the value of s

$s = ut + \frac{1}{2} a {t}^{2}$

plug the values

$= 14 \times 4 + \frac{1}{2} \times 8 \times {4}^{2}$

Reduce the numbers with G.C.F 2

$= 14 \times 4 + 4 \times {4}^{2}$

Multiply the numbers

$= 56 + 4 \times {4}^{2}$

Calculate the product

$= 56 + {4}^{3}$

Evaluate the power

$= 56 + 64$

Add the numbers

$= 120$

Hope this helps..
