Answer:
Jesse can pack 18 books.
Step-by-step explanation:
2.4*18=43.2+5.7==48.9
you cant fit more than fifty becaue 48.9+2.4=51.3, thus 18 is your answer
Step-by-step explanation:


5(a-3)(a-3)
5(a-3)^2

X^4(2x+1) - (2x+1)
(x^4-1)(2x+1)
(x^2-1)(x^2+1)(2x+1)
(x-1)(x-1)(x^2+1)(2x+1)
Answer:
Radius, r = 61 cm
Step-by-step explanation:
According to the attached figure, we have,
Length of chord, AB = 22 cm
Such that, AP = PB = 11 cm
OP = 60 cm
It is required to find the radius of the circle. We know that radius of a circle is perpendicular to chord. So, APO forms a right angled triangle. Using Pythagoras theorem to find the radius of circle. Let it is r. So,

So, the radius of the circle is 61 cm.
Answer:
51 cm^2
Step-by-step explanation:
the formula for area of an icoselese triangle is
A = b * h / 2
h is a line from the angle where the 5 and 5 intersect to the middle of the third line
You can find h using the pythagoran theorm with the 5 being the hypotenuse and the a being half the third line
4^2 + b^2 = 5^2
16 + b^2 = 25
b = 3, so h = 3, so now
A = 8 * 3 / 2
A = 24 / 2
A = 12 cm^2
now we have the triangle, just multiply that by 2 (top and bottom)
12 * 2 = 24
sides
8 * 1.5 = 12
5 * 1.5 * 2 = 15
now add all of it
15 + 12 + 24 = 51
