Answer: x=45
Step-by-step explanation:
Solve for c get 20 c=b so b+115 =135 180-135=x
Answer:
B. 14
Step-by-step explanation:
To determine whether a triangle or not, use the triangle inequality theorem. Two smaller sides must add up and be greater than the larger side.
13+7=20 wouldn't work
14+7>20 would work
7+20=27 wouldn't work
7+20<28 wouldn't work
Calculate the slope using the slope formula
m = (y2-y1)/(x2-x1)
m = (5-(-1))/(-6-(-8))
m = (5+1)/(-6+8)
m = 6/2
m = 3
The slope is 3
The point your teacher uses is (-6,5) because of the y-5. Note how it's in the form y-y1 where y1 = 5
So (x1,y1) = (-6,5)
Point Slope Form
y-y1 = m(x-x1)
y-5 = 3(x-(-6))
y-5 = 3(x+6)
The equation in point slope form is
y-5 = 3(x+6)
So you'll type 3(x+6) into the box
Answer:
2np + p²
Step-by-step explanation:
The general formula for the area of a square is A = s², where s = the length of one side of the square. In the case of the smaller square the area would be: n x n = n². Since the side of the larger square is 'p' inches longer, the length of one side is 'n + p'. To find the area of the larger square, we have to take the length x length or (n +p)².
Using FOIL (forward, outside, inside, last):
(n + p)(n+p) = n² + 2np + p²
Since the area of the first triangle is n², we can subtract this amount from the area of the larger square to find out how many square inches greater the larger square area is.
n² + 2np + p² - n² = 2np + p²
