Answer:
8 square units
Step-by-step explanation:
The base is on a horizontal line. The points are 7-3 = 4 units apart.
The side perpendicular to the base is a vertical segment 6 -2 = 4 units long.
The area is ...
A = 1/2bh
A = 1/2(4 units)(4 units) = 8 units²
The area of the triangle is 8 square units.
__
It is effectively half of a square that is 4 units on a side. 1/2(4²) = 8.
For this case we have the following system of equations:

We can write a system of equivalent equations.
For this, it is enough to multiply one of the two equations by a scalar.
Multiplying the equation 1 by 2, we have:

Therefore, the new system of equations is:

Answer:
A system that is equivalent is:
D) 
Answer:
Theres no equation here?
Step-by-step explanation:
C = circumference of circle
p = perimeter of square
c + p = 29
p = 29 - c
side of square = (29 - c)/4
radius of circle = c/(2pi)
a = side^2 + (pi)r^2
a = ((29 - c)/4)^2 + pi * (c/(2pi))^2
a = (1/16)(841 - 58c + c^2) + (c^2/(4pi^2)) * pi
a = 52.5625 - 3.625c + c^2/16 + c^2/(4pi)
Since the 2nd degree term has a positive coefficient is positive, this has a graph that is a parabola opening up. It has a minimum value.
We take the derivative of the area expression and set equal to zero to find the minimum circumference.
da/dc = -3.625 + c/8 + (c/(2pi)) = 0
c = 12.76
Answer: 12.76 cm
I think u have to Multiply the 100 and 0.30 and that would be 30
