Answer:
f(x + 3) = x² + 3x - 2
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Expand by FOIL (First Outside Inside Last)
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x² - 3x - 2
f(x + 3) is x = x + 3
<u>Step 2: Find</u>
- Substitute: f(x + 3) = (x + 3)² - 3(x + 3) - 2
- Expand by FOILing: f(x + 3) = x² + 6x + 9 - 3(x + 3) - 2
- Distribute 3: f(x + 3) = x² + 6x + 9 - 3x - 9 - 2
- Combine like terms: f(x + 3) = x² + 3x - 2
The Solution is 5.68 x 10^5
Answer:
The ratio of sides in a 30-60-90 triangle is 1:√3:2. Since the shortest side is the 1 in this case the other lengths are 15√3 and 30.
Answer:
i would be -2
Step-by-step explanation:
-25p-2=48
+2 +2
-25p=50
p=-2
Answer:
A) The side is 14 cm
B) The total distance around the whoole board is 56 cm
Step-by-step explanation:
So we know its a square.
A square is all equal sides
We got the area which is 196
So we know area of a square is L*W or S^2
And since all sides are equal we can square root 196
That would give you 14
So we know each side is 14
Part B is just perimeter, there are 4 equal sides so we can just multiply 14*4 which is 56.
CHECK:
So we want to check the sides are equal
Each side is 14
and area is 196
14*14=196
So its true
