well, we can say that √2 and √7 are irrational numbers, they do not provide a value that can be written in a "ration" or fractional.
we can also say that √2 * √7 is √(14), which is also irrational.
However, how about √7 * √7, that's √7² or namely just 7, and that's a rational, so nope, not always.
Answer:
4:5
Step-by-step explanation:
Binh's = 40
Davina's = 50
40:50 = 4:5
Answer:
3) x^2-yz/z^2
x = -3, y = 5 and z = -2 plug in these values
-3^2 -5(-2) /-2^2
= -1/4
decimal form: -0.25
4) x^2+y^2+z^2/xyz
x = -3, y = 5 and z = -2 plug in these values
-3^2+5^2+-2^2/-3*5*-2
= 2/5
decimal form: 0.4
5) x+y/z + y+z/x
x = -3, y = 5 and z = -2 plug in these values
(-3+5/-2)+(5+(-2)/-3)
= -2
6) 2x+y-z/x-3y+z
x = -3, y = 5 and z = -2 plug in these values
2(-3)+5-(-2)/-3-3(5)+(-2)
= -1/20
decimal form: -0.05
If f(x) = -2x + 2, f(5) can be found by substituting in the value 5 for x in the equation:
f(5) = - 2(5) + 2
Our first step in simplifying this expression is to perform the multiplication as outlined by the order of operations (PEMDAS).
f(5) = -10 + 2
Finally, we must get our final answer by adding together the remaining terms.
f(5) = -8
Hope this helps!
We have an isosceles triangle and 2 lines that are drawn through some ( any ) point on the base. The both lines are parallel to one of the legs. Then those lines with the legs of the triangle make a parallelogram. We can say that x and y are the sides of the parallelogram. Then: x + y = 5 in. And the perimeter of the parallelogram: P = 2 x + 2 y = 2 * ( x + y ).
P = 2 * 5 =
10 in. The rest is in the attachment.
Answer: The perimeter of the constructed parallelogram is 10 inches.
