ill give brainiest to first answer

Answer 1

Answer:

0

4

15

27

Step-by-step explanation:

a) The first expression is

$50-b^2+a$

When a=2 and b=5, we get

$50 - {(5)}^{2} + 2 = 50 - 25 + 2 = 27$

b) The second expression is

$a^2(5-b)$

We substitute a=2 and b=5;

${2}^{2} (5 - 5) = 4(5 - 5) = 4 \times 0 = 0$

c) The next expression is

${b}^{2} - 10$

We substitute b=5 to get:

${5}^{2} - 10 = 25 - 10 = 15$

d) The fourth expression is

$a(b-3)$

When a=2 and b=5

$2(5 - 3) = 2 \times 2 = 4$

We know that:

0<4<15<27
