Answer:
(p - 5)(p + 1)
Step-by-step explanation:
Given
p² - 4p - 5
Consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)
The factors are - 5 and + 1 , since
- 5 × + 1 = - 5 and - 5 + 1 = - 4, then
p² - 4p - 5 = (p - 5)(p + 1) ← in factored form
The standard form of a trinomial is
ax² + bx + c ( a ≠ 0 )
p² - 4p - 5 ← is in standard form
with a = 1, b = - 4 and c = - 5
9 5/6 - 2 1/3
9 5/6 - 2 2/6
9 - 2 = 7
5/6 - 2/6 = 3/6
7 3/6
3/6 = 1/2
7 1/2
Answer:
x=3
Step-by-step explanation:
f(x) = 2^x
Let f(x) =8
8 = 2^x
Rewriting 8 as 2^3
2^3 = 2^x
The bases are the same so the exponents are the same
3=x
Answer:
9/16
Step-by-step explanation:
1) convert 1/8 into 2/16 so denominator are the same
2) then you just add the fractions
Answer:
<em>B) x = 3</em>
Step-by-step explanation:
lets plug in the first option to see if it works
3x=9
3*27=9
<em>thats not right</em> ( 3*27 = 81 )
Next, we try the second option
3x=9
3*3=9
<em>that looks more like a resonable answer right?</em>
<em>now to check our work</em>
3+3+3=9
<em>Its correct!</em>
<em></em>
<em>Hope that helps</em>
