Simplify and select the answer with the appropriate restrictions for the variables.
5x2−4x3x3
Answer:-4x/6 + 5x/2
Step-by-step explanation:
just combined it
Factor: 0.25x^2 - 0.16y^4
0.25x^2 - 0.16y^4
Both terms are perfect squares so use the difference of squares formula
A^2 - b^2 = (a+b)(a-b) where a = 5x and b = 4y^2
Answer is 0.01(5x + 4y^2)(5x-4y^2)
Answer:
Solution given:
0.25x^2 - 0.16y^4
[0.5x]²-[0.4y²]²
[Note: Using formula: x²-y²=(x+y)(x-y)]
(0.5x+0.4y²)(0.5x-0.4y²) is a required answer.
which of the following can be added without altering any of the fractions?
a. 3x/x-1 + 8/x-1
b. 6x+1/4x-8 + 1/4x+1
c. 6x/x+6 + 6x/x-6
d. 6x/x-7 + x-7/6x
Answer:
a
Step-by-step explanation:
[tex]\frac{3x}{x-1}[/tex] + [tex]\frac{8}{x-1}[/tex]
These fractions have a common denominator and so do not require to be altered.
The numerators can be added to simplify, that is
= [tex]\frac{3x+8}{x-1}[/tex]
The remaining fractions have different denominators and would require to be altered before they could be added.

EASY MATH!!! GIVING BRAINLIEST!!
Answer:
55
Step-by-step explanation:
So lets take our 50 dollars.
Next, take your increase of 5%. Remember, 5% is 0.05, and it is a increase of 5%, so we are multipling 50 by 1.05.
Before we start multiplying, lets recall that this occurs twice(2 years), but this doesnt mean we multiply 50 by 1.10. No, we just mutiply 50 by 1.05 2 times:
50*1.05
=
52.5
52.5*1.05
=
55.25
So your answer is 55 dollars(rounding down).
Hope this helps!

What are 3 completed examples for systems of equations?
Answer:
There are three ways to solve systems of linear equations: substitution, elimination, and graphing.
if the center of a circle is (-5, -8) and contains the point (16, 68) what is the equation ?
Answer:
[tex](x+5)^2+(y+8)^2=6217[/tex]
Step-by-step explanation:
Hi there!
Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex] where the circle is centered at (h,k) and r is the radius
1) Plug the center of the circle into the equation
Center: (-5,-8)
[tex](x-h)^2+(y-k)^2=r^2\\(x-(-5))^2+(y-(-8))^2=r^2\\(x+5)^2+(y+8)^2=r^2[/tex]
2) Determine r²
Plug in the given point (16,68)
[tex](x+5)^2+(y+8)^2=r^2\\(16+5)^2+(68+8)^2=r^2\\(21)^2+(76)^2=r^2\\441+5776=r^2\\6217=r^2[/tex]
Therefore, r² is equal to 6217. Plug this back into [tex](x+5)^2+(y+8)^2=r^2[/tex]:
[tex](x+5)^2+(y+8)^2=6217[/tex]
I hope this helps!

There is 2/3 of a pan of brownies left on the
counter. If you eat 2/3 of the brownies left in the
pan, what is the fraction of the whole pan that
you ate?
Answer:
He ate 4/9 of the pan of brownies.
Step-by-step explanation:
So the question might seem hard but when you read it, it said that there were 2/3 of brownies left and he ate 2/3 of that 2/3 in that pan so to figure 2/3 of 2/3 I divided 2/3 by 3 which is 2/9, 2/9 is 1/3 of 2/3 to figure out 2/3 of 2/3 you need to add by itself which you get 4/9.

Answer:
3.2
Step-by-step explanation:
Answer: 3.3
Step-by-step explanation: To find x(adjacent)we need to know the length of the opposite ,and to do so we use the dimensions of the larger triangle,let's say A.
So using SOHCAHTOA
Sin=opposite÷hypotenus . Meaning
Opposite =hypotenus×sin
=9×sin31°
=4.635... which is rounded to 4.64.
Finding x
From tan=opposite÷adjacent
adjacent=opposite÷tan
=4.64÷tan55°
=3.2489.... which is rounded to 3.3
