Evaluate the algebraic expressions, and put their values in order from least (1) to greatest (4), for a = 2 and b = 5 1. 50 − b2
Black_prince [1.1K]

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
