Answer:
100 cm
Step-by-step explanation:
Given:
AC = BC
AC = 40
2AB=AC
Simplify:
BC = 40
Simplify:
2AB = 40
Algebra:
AB = 20
Here's the sides:
AB = 20
AC = 40
BC = 40
Add all of them together:
100
Answer: p = 120 degrees
Step-by-step explanation:
Figure a shows a pentagon. The sum of interior angles in a pentagon is equal to 540 degrees.
1. Subtract the known numerical angle
540 - 60 = 480
All of the remaining angles (represented by the variable p) are equal to one another. Therefore, we can use the expression 4p = 480 to find the value of p.
2. Evaluate the equation to find the value of p.
4p = 480
p = 120
The factored version of the above statement would be 5(x + 4)
In order to find this, you need to find the greatest common factor of the two coefficients. First, list the factors of each.
Factors of 5: 1, 5
Factors of 20: 1, 2, 4, 5, 10, 20
Since the highest that exists in both lists is 5, we can divide both terms by 5 and pull it out of the parenthesis like this:
5(w + 4)
Which is your final answer
area = x^2 - 4x + 3

Its B
All you have to do is subtract 10-12 = -2 and 2(5-6) = -2 how? Subtract 5-6 that will equal to -1 now -1 x 2 = -2
