Answer:
x^4 - 8 x^2 + 16
Step-by-step explanation:
Use formula (a-b)^2 = a^2-2ab+b^2
now a=4 b=x^2, plug in
Hey there,
The whole number(or mixed fraction) would be: 1 2/3

Answer:

Step-by-step explanation:
Let's call B at the base of the triangle and call h at the height of the triangle. Then we know that:
The height of a triangle is 5 cm shorter than its base. This means that:
.
The area of the triangle is 25 cm²
By definition the area of a triangle is:

For this triangle we know that
and
. We substitute these values in the equation and solve for B.


Now we use the quadratic formula to solve the equation.
For an equation of the form
the quadratic formula is:

In this case note that: 
Then:



The solutions are:


For this problem we take the positive solution.

Now we substitute the value of B in the equation to find the height h


Answer:
surface area of cube is 6a² where a is side of the cube
Answer:
Step-by-step explanation:
Alright, lets get started.
When two secants intersects outside a circle then the measure of the angle formed is half of the positive difference of the measures of the intercepted arcs. (Please refer the diagram I have attached)
Hence the measure of ∠1 is :
∠1=
∠1=
hence the answer is 35°. : Answer
Hope it will help :)
