Answer:
x = 34
Step-by-step explanation:
The 3 given angles form a straight angle and sum to 180°, hence
x + 12 + 100 + x = 180
2x + 112 = 180 ( subtract 112 from both sides )
2x = 68 ( divide both sides by 2 )
x = 34
Answer:
C. I > 4 (or x > 4)
Step-by-step explanation:
first multiply 8 and (x - 5)
8(x– 5) – 3x > -20 -----> (8 * x) - (8 * 5) = 8x - 40 - 3x > -20
add like terms
8x - 40 - 3x > -20 -----> 8x + -3x = 5x - 40 > -20
combine -40 and - 20
5x - 40 > -20 ----> -20 + 40 = 5x > 20
Then finally divide
5x > 20 -----> (5x/5) > (20/5) = x > 4
Area of triangle = 1/2 x base x height
so old triangle we have 1/2 x b x h = 48
new triangle has base 3 times as long and height is half as long
so we would get:
1/2 x (3B) x (1/2H) = area
rewrite as 1/2 x 3/2 x b x H = area
divide by original are os 1/2 x b x h and you end up with 3/2
so new area = 3/2 x old area
new area = 3/2 * 48 = 72 square inches
Answer:
Step-by-step explanation:
A point in geometry is a location. It has no size i.e. no width, no length and no depth. A point is shown by a dot. A line is defined as a line of points that extends infinitely in two directions. ... A plane extends infinitely in two dimensions
I hope this helps you
f (x)=x^2 (x^2-1)
f (x)=x^2 (x-1)(x+1)
