The polynomial which should be filled in the blank is (x - 2).
What are Polynomials?Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.
Given that,
x² - 4 = (x + 2) (x - 2).
We have to find the blank space.
By commutative property, the other side is also equal.
That is,
(x + 2) (x - 2) = x² - 4
Hence the correct option is (x - 2).

Three-fifths of the students in a room are girls. One-third of the girls have blond hair. One-half of the boys have brown hair. What fraction of all the students are girls with blond hair?
Answer:
1/5
*I'm sorry if I got it wrong, but if not I hope this helps!*
Step-by-step explanation:
since 3/5 of the students are girls, and 1/3 of the girls have blonde hair, to find what fraction of all the girls have blond hair, we would multiply 3/5(1/3)
3/5(1/3)=3/15=1/5
therefore, 1/5 of all the students are girls with blond hair

CAN SOMEONE PLEASE FIND THE VOLUME AND SURFACE AREA OF THIS FIGURE.
and round to the nearest hundredth
Answer:
Volume = 1659.84Surface area = 1205.36Step-by-step explanation:
Volume for triangular prism = 1/2 * b * l * h
we are given the length and the height but not the base.
since it is a right triangle we can use the Pythagorean theorem a^2 + b^2 = c^2
13.3^2 + b^2 = 20.5^2
176.89 + b^2 = 420.25
b^2 = 243.36
b = [tex]\sqrt{243.36}[/tex] = 15.6
1/2 (15.6)(13.3)(16) = 1659.84
Front: 15.6 x 13.3 = 207.48
Back: 15.6 x 13.3 = 207.48
Left: 15.6 x 16 = 249.6
Right: 13.3 x 16 = 212.8
Bottom: 20.5 x 16 = 328
207.48 + 207.48 + 249.6 + 212.8 + 328 = 1205.36

Lea,Paul and Tynos invest in a business in the ratio 2:3:5.if the profit from the business is $450 000.how much does each person get?
Answer:
see explanation
Step-by-step explanation:
Sum the parts of the ratio, 2 + 3 + 5 = 10 parts
Divide the profit by 10 to find the value of one part of the ratio.
$450 000 ÷ 10 = $45 000 ← value of 1 part of the ratio, then
2 parts = 2 × $45 000 = $90 000 ← Lea's share
3 parts = 3 × $45 000 = $135 000 ← Paul's share
5 parts = 5 × $45 000 = $225 000 ← Tynos' share

Answer:
m<ADC = 107
Step-by-step explanation:
You need to know three things to solve this problem.
1) Opposite angles of an inscribed quadrilateral are supplementary.
2) The measure of an inscribed angle is half the measure of its subtended arc.
3) The sum of the measures of all the arcs of a circle is 360 deg.
From 1) we get:
m<A + m<C = 180
72 + m<C = 180
m<C = 108
From 2) we get:
m<C = (1/2)m(arc)BAD
108 = (1/2)[m(arc)AB + m(arc)AD]
216 = m(arc)AB + 122
m(arc)AB = 94
From 3) we get:
m(arc)AB + m(arc)BC + m(arc)CD + m(arc)DA = 360
94 + 120 + m(arc)CD + 122 = 360
m(arc)CD = 24
From 2) we get:
m<ADC = (1/2)m(arc)ABC
m<ADC = (1/2)[m(arc)AB + m(arc)BC]
m<ADC = (1/2)[94 + 120]
m<ADC = 107

Answer:
10 in by 48 in
Step-by-step explanation:
The volume (V) of a rectangular solid is calculated as
V = Ah ( A is the area of the base and h the height )
Here h = 3 and V = 1440 , then
3A = 1440 ( divide both sides by 3 )
A = 480 in²
The area of a rectangle = length × breadth
From the give options
10 × 48 = 480 ← is the only option
