Answer:
B. 5x^2 -4
Step-by-step explanation:
(f+g)(x) = f(x) + g(x)
= (4x^2 +1) +(x^2 -5) . . . . . . substitute for f(x) and g(x)
= x^2(4 +1) +(1 -5) . . . . . . . . collect terms
(f+g)(x) = 5x^2 -4
Im pretty sure its -4 soz if im wrong
best of luck (:
Step-by-step explanation:
Given data:
ABCD is a quadrilateral.
AD = BC – – – – (1)
∠DAB = ∠CBA – – – – (2)
<u>To prove that BD = AC:</u>
In ΔABD and ΔBAC,
AD = BC (given side)
∠DAB = ∠CBA (given angle)
AB = BA (reflexive side)
Therefore ΔABD ≅ ΔBAC by SAS congruence rule.
By corresponding parts of congruence triangles,
BD = AC
Hence proved.
