Answer:
4
Step-by-step explanation:
To find the area of a rectangle, you multiply adjacent side lengths, so in this case it would be (x + 3)(4x - 7) which expands to 4x^2 + 5x - 21.
Step-by-step explanation:
here
f(x)=x^2+6
Now
Replacing the value of x
f(3x)=3x^2 +6
Answer:
15
Step-by-step explanation:
the equation would be p=6x where x is the side length.
2 11/16 I believe is the answer
Answer:
D. Obtuse.
Step-by-step explanation:
We are told that in
and
. We are asked to classify our given
.
We can see that angle M and angle P are acute angles as their measure is less than 90 degrees.
Let us find the measure of angle P using angle sum property of triangles, which states that sum of interior angles of a triangle is 180 degrees.
So we can set an equation as:

Upon substituting our given values we will get,




As measure of angle N is 98 degrees, so angle N is an obtuse angle.
Since a triangle having an angle that measures more than 90 degrees is called an obtuse triangle, therefore,
is an obtuse triangle and option D is the correct choice.
