Answer:
no
Step-by-step explanation:
z^2 +1=4+3z
Substitute into the equation and see if it is true
3^2 +1 = 4+3(3)
9+1 = 4+9
10 = 13
This is not a true statement so this is not a solution
Answer:
m∠2=9
Step-by-step explanation:
Hello There!
The problem states that the angles are complementary angles
Complementary angles are angles that have measures that add up to equal 90
So given one of the angles we can find the missing angle by subtracting the known angle from 90
90 - 81 = 9
so we can conclude that the measure of angle 2 is 9

Answer:
Area is 364
Step-by-step explanation:
A parallelogram's area is equal to base times height. So it doesn't depend on the angle at all, as long as the base and height are constant.
That means that the area of the parallelogram on the left is the same as if it was a rectangle (an extension of the rectangle part on the right).
This brings us to the answer - the area is the same as the area of a 14x26 rectangle.
14*26=364
Alternatively, let's compute the area of the rectangle on the right:
18*14 = 252
And the area of the parallelogram
14 * (26-18) = 14*8 = 112
And the area of the composite figure is 252+112 = 364
Suppose
has two roots, reciprocals of one another. Call them
, with
.
Let's divide through
by
for now. By the fundamental theorem of algebra, we can factorize
as
Expand the RHS to get
so we must have
The first equation says
and
occur in a ratio of the negative sum of the roots of
, while the third equation says that the first and last coefficients
must be the same.
