Answer:
10√2
Step-by-step explanation:
Lets cut the square into a triangle, making a line from one corner to another, then let's see what we have.
We shoupd have a triangle where we don't know the hypotenuse, which we can find using the formula: a^2 + b^2 = c^2
so:
10^2 + 10^2 = c^2
100 + 100 = c^2
c^2 = 200
now let's square root what we got
√200
there are 2 10's in 200, which will turn the equation to:
10√2
this can't be simplified further, so our answer is 10√2
Answer:
x = - 2, x = 10
Step-by-step explanation:
Given
x² - 8x - 20 = 0
Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 8)
The factors are - 10 and + 2 , since
- 10 × 2 = - 20 and - 10 + 2 = - 8 , then
(x - 10)(x + 2) = 0
Equate each factor to zero and soilve for x
x + 2 = 0 ⇒ x = - 2
x - 10 = 0 ⇒ x = 10
