Answer:
A
Step-by-step explanation:
A]
7*5 = 35+15 = 50
10*70 = 70 +14 = 85
15*7 = 105 +15 = 120
20*7 = 140+15 = 155
B]8.50*5 = 42.5
C]10*5 = 50
10*10 = 100
D] = 8*5 = 40 +10 = 50
10*8 = 80+10 = 90

A)
If it has an area of 4(x+3) we can think that one side has a length of 4, and the other has a length of (x+3).
So, if the dimensions were doubled, 4 x 2 = 8. And 2(x+3) = 2x+6.
The new area would be:
8(2x+6) = 16x+48.
B)
The ratio will be the same. For example lets plug in some points:
x=0
4(0+3) = 4(3) = 12
And
16(0)+48 = 0+48 = 48
So the ratio is 48/12 = 4
Lets plug in another point.
x=2
4(2+3)= 4(5) = 20
And
x=2
16(2)+48 = 32 + 48 = 80
80/20 = 4
So the ratio is the same :)

Answer: FALSE
Step-by-step explanation:
The first step is to rewrite the equation in the form 
, then:
Now, we need to calculate the Discriminant with this formula:
We can identify in the given equation that:
Then, we only need to substitute these values into the formula:
Since 
then the equation has no real solutions.
