What is the solution set of the equation

cupoosta [38]

Answer:

Step-by-step explanation:

Given

x² + 3x - 4 = 6 ( subtract 6 from both sides )

x² + 3x - 10 = 0 ← in standard form

Consider the factors of the constant term (- 10) which sum to give the coefficient of the x- term (+ 3)

The factors are + 5 and - 2, since

5 × - 2 = - 10 and 5 - 2 = + 3, thus

(x + 5)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 2 = 0 ⇒ x = 2

solution set is { - 5, 2 } → A

AD ??????? so confused what the

Andre45 [30]

Answer:

3.6 cm

Step-by-step explanation:

<u>Triangle Proportionality Theorem</u>

BD : DE = BA : AC

⇒ 6 : 10 = BA : 16

⇒ $\mathsf{\dfrac{6}{10} = \dfrac{BA}{16}}$

⇒ $\mathsf{BA=\dfrac{6}{10} \times16}$

⇒ BA = 9.6

AD = BA - BD

⇒ AD = 9.6 - 6 = 3.6 cm
