Answer:
1. 51
2. 8
3. √2 or 1.41
Step-by-step explanation:
using pythagorean theorem
We have f(x) = 0;
Then x^2 - 1 - 2x - 2 = 0;
(x - 1)(x + 1) - 2(x + 1) = 0;
(x + 1)(x - 1 - 2) = 0;
(x + 1)(x - 3) = 0;
x + 1 = 0 or x - 3 = 0;
x = -1 or x = 3;
The zeroes of f are -1 and 3.
Answer:
16.34
Step-by-step explanation:
To find the answer, you multiply 3.8 (how much is in one gallon) by 4.3 (number of gallons) to get the answer of 16.34.

So,
Reggie has enough flour to last for 40 days.
Increasing his use of flour by 25% will reduce how many days of flour he will have by 25%, leaving him with 75% of the original number of days of flour left. We can do simple multiplication to find our result.
If Reggie increases his use of flour by 25%, he will have 30 days' worth of flour.
Answer:
<x = 53 degrees
Step-by-step explanation:
<Q = 62 degrees (alternate angle)
<PRQ = 180-115 (Angles on a straight line add up to 180 degrees)
<PRQ = 65 degrees
<u><em>Now, Finding <x</em></u>
To find <x, we'll simply subtract 180 from rest of the triangles interior angles because the interior angles of a triangle add up to 180 degrees
=> <x = 180-65-62
=> <x = 53 degrees
