Answer:
350
Step-by-step explanation:
629= A+S
A-71 = S
629 = A+A-71
700=2A
A=350
Answer:
A
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
Answer:
3.6 cm
Step-by-step explanation:
<u>Triangle Proportionality Theorem</u>
BD : DE = BA : AC
⇒ 6 : 10 = BA : 16
⇒ 
⇒ 
⇒ BA = 9.6
AD = BA - BD
⇒ AD = 9.6 - 6 = 3.6 cm
