Answer:
A.
Step-by-step explanation:
The trinomial
is of the form
. Then, it can be factored by searching two numbers that added are -12 and multiplied are 35. Those numbers are -7 and -5. Then,

So, the answer is A.
Answer:

Step-by-step explanation:
We are given that endpoints of a diameter at the points (7,2) and (-9,5).
Center of the circle is the mid point of diameter
So, first find the mid point of diameter
Formula : 

Substitute the values in formula


So, center of circle = (h,k )=(-1,3.5)
To find length of diameter :




Length of radius = r = 
Standard form of the equation of the circle : 
(h,k )=(-1,3.5)

Equation of the circle : 
Equation of the circle : 
Hence the standard form of the equation of the circle with endpoints of a diameter at the points (7,2) and (-9,5) is 
Answer:

Answer:
The length of each of the other two sides would be 3.1 cm
Step-by-step explanation:
<u><em>The options of the question are</em></u>
A. 3.1 cm
B. 3.2 cm
C. 4.2 cm
D. 6.1 cm
we know that
An isosceles triangle has two equal sides and two equal interior angles
Let
x -----> the length of each of the two equal sides in the isosceles triangle
The perimeter of one isosceles triangle is equal to

Remember that
To maximize the use of the wire, the perimeter of 6 earrings (3 pairs of earrings) must be equal to 50 cm
so

Solve for x




therefore
The length of each of the other two sides would be 3.1 cm
