Perpendicular lines have a slope that is the opposite reciprocal of the given slope. This means the new slope is -2.
Then you plug in the point to get your new y intercept 10=(-2)7+b
You solve by first multiplying -2 and 7 to get 10=-14+b
Then you add 14 on both sides to get 24=b
You plug this into the equation with your new slope to get y=-2x+24
No, they are not the area of the first triangle is 24 because 1/2*b*h so 1/2*6*8 + 24 and the area of triangle #2 is 1/2*8*12 is 48.
Hope this helped!
Ok so to find the sum of interior angles the formula is
s=180(n-2)
s is sum and n is the number of sides
so this is a quadrilateral cause it has 4 sides
because of that n=4
substitute
s=180(4-2)
now you can either distribute or do pemdas but its easier and more efficient to just do pemdas
s=180(2)
s=360 degrees
Answer:
x
^2 + 11 x + 30
Step-by-step explanation:
Expand the polynomial using the FOIL method.
x^2 + 6x + 5x + 30
Collect the like terms
x^2 + (6x + 5x) + 30
Simplify
x
^2 + 11 x + 30
Hope this helps :)
I believe the answer is D. 25 and 27
