Answer:
The first answer is no
two varying quantities are said to be in a relation of proportionality you can't divide 50 into 6 and get a proportional number
The second answer is yes because they are all equal and make a straight line
Step-by-step explanation:
Answer:
Y = 60 because a equallateral triangle is always 60˚ I don't know x though
Answer:
7x^2y^3z^5(x^2y^5 + 2z^6)
Step-by-step explanation:
7x^4 y^8 z^5 + 14x^2 y^3 z^11
try to get the smallest of each number and variable outside if that makes any sense
14 can go into 7 two times so take out 7 and multiply it by the whole thing
7(x^4 y^8 z^5 + 2x^2 y^3 z^11)
then x y and z
7x^2y^3z^5(x^2y^5 + 2z^6)
sorry its kinda hard to see exponents in this form hopefully this helps
Answer:
the length of the rectangle is, 21 in.
Step-by-step explanation:
Area of the rectangle(A) is given by:
.....[1]
where,
l is the length of the rectangle
w is the width of the rectangle.
As per the statement:
The width of a rectangle is 9 in. shorter than its length.
⇒
It is also given that:
The area of the rectangle is 252 in².
⇒A = 252 in².
Substitute in [1] we have;
⇒
⇒
Factorize this equation:
Split the middle term;
⇒
⇒
⇒
By zero product property we have;
and
⇒ and
Since, length cannot be in negative
⇒
Therefore, the length of the rectangle is, 21 inches.
