Answer:
Exact Form:
7/10
Decimal Form:
0.7
Therefore the answer would be "B".
Step-by-step explanation:
You get this answer by DIVIDING.
Let's call the width
. Since the length is three more than the width, it is
.
The area (which we know to be 70) is given by the multiplication of width and length:

To solve this equation, you can use the usual quadratic formula: given an equation
, the two solutions are

which in your case becomes

So, two solutions are

Since we can't accept a negative length, we only accept the second solution.
So, the dimensions are 7 and 10
Answer:

Step-by-step explanation:

Answer:
(x + 7)^2 + (y + 3)^2 = 4
Step-by-step explanation:
The standard equation of a circle is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius. We can substitute the information given to obtain:
(x + 7)^2 + (y + 3)^2 = 4
Answer:
b= -1.6
When you do inverse operations, (-1)-0.6= -1.6
