which expression results from using the Distributive Property? 6(x+4)
Answer:
6x + 24
Step-by-step explanation:
Distributive property means that multiply the bracket multiplies each part inside and keeps the signs the same:
6 * x = 6x
6 * 4 = 24
Answer:
6x+24
Step-by-step explanation:
6(x+4)
Distribute the 6 to each term inside the parentheses
6*x + 6*4
6x+24

Q5. Asif is 5 years younger than Qasim. Four years later, Qasim will be twice as old as
Asif. Find their present ages.
Answer:
Age of Qasim = 6 year
Age of Asif = 1 year
Step-by-step explanation:
Let :
Age of Qasim = x
Age of Asif = x -5
After 4 years there age will be:
Age of Qasim = x+4
Age of Asif = x-5+4 = x-1
We are given: Four years later, Qasim will be twice as old as Asif.
Age of Qasim = 2 (Age of Asif)
x+4=2(x-1)
x+4=2x-2
2x-x=4+2
x=6
So, We get x = 6
The present ages will be:
Age of Qasim = x = 6 year
Age of Asif = x -5 = 6-5 = 1 year

Dante's family has completed 40% of a trip. They have traveled 25 miles. how far is the entire trip?
Answer: The entire trip is 62.5 miles
Step-by-step explanation:
25 miles = 0.4x
Divide both sides by 0.4
25/0.4 = 62.5 miles
Value of x. Pleaseeeeeeeeeeeeeee
Answer:
x=62
Step-by-step explanation:
all angles should add to 180
180-56=124
124÷2=62
Answer:
Step-by-step explanation:
1st notice that two of the sides are the same length? ( isosceles ) that mean the two angles at the "base" which is the side that both of the same size legs tie into... that's the side that is 4.5 in the picture. soooo if both of those angles are the same.. and we know that the angles are going to add to 180 then.... we can say the the 56° is the same as the one at the other end of the 4.5 side (base) so 2*56°=112°
and then 112° + x = 180°
x = 180-112
x = 68°

Step-by-step explanation:
Rate of Change
The average velocity is defined as the rate of change of the distance with respect to time. The table shows the distances of an object as a function of time.
It's required to find the average velocity between 8 s and 20 s.
The rate of change can be approximated as the slope between two points. We take from the table the points (8,32) and (20,10) and calculate the slope.
The slope can be calculated with the equation:
[tex]\displaystyle v=\frac{d_2-d_1}{t_2-t_1}[/tex]
[tex]\displaystyle v=\frac{10-32}{20-8}=\frac{-22}{12}[/tex]
Simplifying:
[tex]\displaystyle v=-\frac{11}{6}[/tex]
Choice: B. [tex]\mathbf{-\frac{11}{6}\ \frac{inches}{second}}[/tex]

find the distance between the pionts(-5,1) and (4,1)
Explanation:
The formula for calculating the distance between two points is: d = √ ( x 2 − x 1 ) 2 + ( y 2 -y 1 ) 2 Substituting the points from the problem gives: d = √ ( 0 − 5 ) 2 + ( 4 − 1 ) 2 d = √ ( − 5 ) 2 + ( 3 ) 2 d = √ 25 9 d = √ 34 Or d =3 5.8 rounded to the nearest hundredth.

Answer:
2. x ≈ 17.74
3. x ≈ 16.64
Step-by-step explanation:
The tangent function relates an angle to the opposite and adjacent sides of a right triangle:
Tan = Opposite/Adjacent
Here, we're looking for the measure of the side opposite the angle, so we can rearrange this relation to ...
Opposite = Adjacent×Tan
__
2. x = 32×tan(29°) ≈ 17.74
3. x = 13×tan(52°) ≈ 16.64

Stefan sells Jin a bicycle for $137 and a helmet for $17. The total cost for Jin is 140% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make bying the bicycle and helmet to Jin? Stefan originally spent $
Answer:
Stefan originally spent $110.
Stefan made a profit of $44.
Step-by-step explanation:
Given that:
Stefan sold the bike and helmet for $137 and $17
Total amount = 137+17 = $154
This is 140% of the price Stefan originally paid.
Let,
x be the original price paid by Stefan
140% of x = $154
[tex]\frac{140}{100}x=154\\1.4x = 154\\\frac{1.4x}{1.4}=\frac{154}{1.4}\\x=110[/tex]
Therefore,
Stefan originally paid $110 for the bicycle and helmet.
Profit made by Stefan = 154-110 = $44
Hence,
Stefan originally spent $110.
Stefan made a profit of $44.

The polynomial p(x)=3x^3-20x^2+37x-20 has a known factor of (x-4). Rewrite p(x) as a product of linear factors. p(x) =
Answer:
[tex]p(x) = (x-4)(x - \frac{5}{3})(x - 1)[/tex]
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
In this question:
We have the polynomial [tex]p(x) = 3x^3-20x^2+37x-20[/tex]
It has a known factor [tex]x - 4[/tex]. This means that the polynomial can be written as:
[tex]p(x) = (x-4)q(x)[/tex]
In which q(x) is a second order polynomial, because p is of the third degree and q is of the first degree(3 - 1 = 2). So
[tex]q(x) = ax^2 + bx + c[/tex]
We have to find a, b and c. Then
[tex]3x^3-20x^2+37x-20 = (x-4)(ax^2 + bx + c)[/tex]
[tex]3x^3-20x^2+37x-20 = = ax^3 + (-4a + b)x^2 + (c - 4b)x - 4c[/tex]
Comparing both sides, we have that
[tex]a = 3[/tex]
[tex]-4c = -20 \rightarrow c = 5[/tex]
[tex]c - 4b = 37[/tex]
[tex]-4b = 32 \rightarrow b = -8[/tex]
Now we find the roots of this polynomial.
[tex]\bigtriangleup = b^{2} - 4ac = (-8)^2 - 4(3)(5) = 64 - 60 = 4[/tex]
[tex]x_{1} = \frac{-(-8) + \sqrt{4}}{2*3} = \frac{5}{3}[/tex]
[tex]x_{2} = \frac{-(-8) - \sqrt{4}}{2*3} = 1[/tex]
So, as a product of it's factors, we have that q is:
[tex]q(x) = (x - \frac{5}{3})(x - 1)[/tex]
And p(x)
[tex]p(x) = (x-4)q(x)[/tex]
[tex]p(x) = (x-4)(x - \frac{5}{3})(x - 1)[/tex]
