Answer:
The correct answer is A. 5(x + 3)(x - 3)
Step-by-step explanation:
In order to solve this, we start by pulling out the greatest common factor.
5x^2 - 45
5(x^2 - 9)
Now we can use the difference of two squares to factor the rest of the equation.
5(x + 3)(x - 3)
Answer:
4 km -> 400,000 mm
put a decimal point at the end of 4 and move it to the left 6 times because we know that 1 km is equal to 100,000 and it has zeros.
hence, it is proven that 4 km is equal to 4000,000.
Answer: He will have 8 1/3 nuts
Step-by-step explanation:
Amount of peanuts=4 2/3 cups
Amount of cashews=3 2/3 cups
Combing the nuts will give Total amount of nuts ( peanuts and cashews)
=4 2/3 +3 2/3
=7 4/3
7 + 1 1/3
8 1/3 nuts
Answer: To solve this you need to use the vertex form of the equation of a parabola which is y=a(x−h)2+k , where (h,k) are the coordinates of the vertex.
