Thepotemich [5.8K]

The number of cars that are in mint condition are = 84

The potential solutions to the radical equation are a = −4 and a = −1. Which statement is true about these solutions? The soluti
inessss [21]

Answer:

Both a = −4 and a = −1 are true solutions

Step-by-step explanation:

Given

\sqrt{a + 5} = a + 3

a = -4; a = -1

Required

The true statement about the solutions

We have:

\sqrt{a + 5} = a + 3

Square both sides

a + 5 = (a + 3)^2

a + 5 =a^2 + 6a + 9

Collect like terms

a^2 + 6a - a + 9 - 5 = 0

a^2 + 5a + 4 = 0

Expand

a^2 + 4a + a + 4 = 0

Factorize

a(a + 4) + 1(a + 4) = 0

Factor out a + 4

(a + 1)(a + 4) = 0

Split:

a + 1 = 0; a + 4 = 0

Solve:

a =-1; a = -4
