Answer:
Option B , D and E are correct.
Step-by-step explanation:
We set the denominator equal to zero to find the number to put in division box
So, if 3 is in the division box then the denominator will be
x-3 = 0 => x=3 is the root.
So, Option E is correct
2x^2-2x-12 ÷ x-3 = 2x+4 is correct.
because after division the result given is 2x+4 which is correct.
So, Option B is correct
x-3 is a factor of 2x^2-2x-12 because because when the term is divided we get the remainder 0.
So, Option D is correct
So, Option B,D and E are correct.
Christopher purchased 2.8 pounds of almonds and 3.5 pounds to roasted pistachios.
Step-by-step explanation:
Cost of almonds per pound = $10
Cost of roasted pistachios = $12
Total amount spent = $70
Weight of nuts = 6.3
Let,
Weight of almonds = x
Weight of roasted pistachios = y
According to given statement;
x+y=6.3 Eqn 1
10x+12y=70 Eqn 2
Multiplying Eqn 1 by 10
Subtracting Eqn 3 from Eqn 2;
Dividing both sides by 2
Putting y=3.5 in Eqn 1
Christopher purchased 2.8 pounds of almonds and 3.5 pounds to roasted pistachios.

Answer:
The area of the larger is 36 units^2
Step-by-step explanation:
The scale factor is 6/3 = 2
When we work with areas, it is scale factor squared
scale factor ^2 = area of larger / area of smaller
2^2 = area of larger / 9
4 =area of larger / 9
Multiply each side by 9
4*9 = 36
The area of the larger is 36 units^2

Well, we know that she could only bend her knee 30 degrees from the start.
And after six weeks of therapy, she can bend it 108 degrees.
So that means: 108 - 30 = 78 degrees more.
