Idk this answer because no triangles are shaded.
Answer:
41x² - 27x + 27
Step-by-step explanation:
Perimeter of Rectangle:
= 2(20x²-12x+4) + 2(5x²-5x+15)
= 40x²-24x+8 + 10x²-10x+30
= 50x²-34x+38
Perimeter of Triangle:
= 6x²+6x+3x+3+3x²-2x+8
= 9x²+7x+11
Difference:
(50x²-9x²)+(-34x+7x)+(38-11)
= 41x² - 27x + 27
Notice, (5,0) and (-4,0), the y-coordinate is 0, namely those are x-intercepts, the vertex is halfway between them, namely the vertex is at 0.5 over the x-axis.
therefore the equation of the axis of symmetry will be the x = 0.5.
Answer:
1.99
Step-by-step explanation:
We have been given the heights of adult men in America are normally distributed, with a mean of 69.8 inches and a standard deviation of 2.61 inches. We are asked to find the z-score of height of man with 6 feet 3 inches.
We will use z-score formula to solve our given problem.
, where,
z = z-score,
x = Sample score,
= Mean,
= Standard deviation,
6 feet 3 inches = 72+3 inches = 75 inches




Therefore, the z-score for the man with height of 6 feet 3 inches is 1.99.
54-36 =18
they can make 18 bouquets
54/18 =3
36/18 =2
18 bouquets with 3 red and 2 white roses each
