Answer:
This means c=100. The factored form is .
Step-by-step explanation:
A perfect square is a trinomial that factors into the form . To find the value of C to finish the perfect square divide 20 by 2 and square it.
20/2 = 10
10*10=100
This means c=100. The factored form is .
Answer:
24 mm
Step-by-step explanation:
Since it is a right triangle, we can use Pythagorean theorem
where a and b are the legs, and c is the hypotenuse.
We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.
Solve the exponents
Now, solve for b. To do this, get b by itself.
First, subtract 100 from both sides
Take the square root of both sides
b=24
So, the other leg is 24 mm
