Answer:
p =
Step-by-step explanation:
Since there are 2 equal roots then the value of the discriminant is zero, that is
b² - 4ac = 0
Given
(q + 1)x² - 8x + p = 0 ← in standard form
with a = q + 1, b = - 8, c = p , then
(- 8)² - 4p(q + 1) = 0
64 - 4p(q + 1) = 0 ( subtract 64 from both sides )
- 4p(q + 1) = - 64 ( divide both sides by - 4 )
p(q + 1) = 16 ( divide both sides by q + 1 )
p =

We are looking for three numbers that make 14, that´s it.
Whole numbers are the only exception, therefore decimals and fractions are excluded.
There are plenty of them out there, but here are my three.
Answer is -4. good luck !
Answer:
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem
Triangles FEG and FHJ are similar by AA Similarity Theorem
see the attached figure to better understand the problem
so
we have
substitute
