Find the missing length. The triangles are similar.
Can someone help me?
Need to show the work
Answer:
28
Step-by-step explanation:
The ratio of the triangles is 12:15 which is equal to 4:5
Then you can use that ratio to find the ?
35 would be the 5 so 4 would be multiplyed by 7
Which is equal to 28

You are a T.V. salesperson who gets an 8% commission. How much commission do you

400 x 8% = $32.00
Step-by-step explanation:
If I was asked to think of a number and multiply it by 2, I could
write this algebraically as 2x.
Write the following algebraically, using x as your unknown.
"I think of a number, multiply it by 2, subtract 3 and multiply the result by 4."
Answer:
4(2x - 3) is how I would write it algebraically.
Step-by-step explanation:
The number is x, as it is unknown. 2x means you multiply the unknown number by 2.
2x
Now, you subtract 3.
2x - 3
And then you multiply the result of that by 4, hence the parentheses.
4(2x - 3)
To solve, just distribute 4. 4*2x = 8x. 4*-3 = -12.
8x - 12
Answer:
8x-12
Step-by-step explanation:
(2x-3)* 4 = 8x-12

Can you please help me solve for x for this triangle please!!
Answer:
See below, please!
Step-by-step explanation:
Since this triangle is a right triangle, the two acute angles are always going to be complementary (adding up to 90 degrees). So we can set up an equation: 2x+3x+5=90. Solve this and we get x=17.
Hope this helped!

José has 3 brown socks, 5 blue socks, and 6 black socks
in his sock drawer. He picked one sock and then another sock out of the
drawer. Are the events independent or dependent? Explain your answer.
Answer:
independent
Step-by-step explanation:
, it has no effect on the number of red socks so thewhen he draws out a sock the event is not affected by the draw a blue sock or the bla ck sock or the brown sock

Answer:
[tex]x^{2}[/tex] - [tex]z^{2}[/tex] - 2z[tex]\sqrt{5}[/tex] - 5
Step-by-step explanation:
This is the equation that you started off with:
(x - z - [tex]\sqrt{5}[/tex])(x + z + [tex]\sqrt{5}[/tex])
You can't really use FOIL on this because that's used in multiplying binomials, and this is a trinomial, but you can still break it up and simplify it this way:
(a + b + c)*(d + e + f) = (a(d + e +f)) + (b(d + e + f)) + (c(d + e + f))
So, applying that idea to the actual equation:
x(x + z + [tex]\sqrt{5}[/tex]) -z(x + z + [tex]\sqrt{5}[/tex]) - [tex]\sqrt{5}[/tex](x + z + [tex]\sqrt{5}[/tex])
= x^2 + xz + x[tex]\sqrt{5}[/tex] -xz -z^2 - z[tex]\sqrt{5}[/tex] - x[tex]\sqrt{5}[/tex] - z[tex]\sqrt{5}[/tex] - 5
= x^2 - z^2 - 2z[tex]\sqrt{5}[/tex] - 5
or [tex]x^{2} - z^{2} - 2z\sqrt{5} - 5[/tex]
CALCULATE ANGLES USING LINE AND ANGLE RELATIONSHIPS:) will mark b for right answer
Answer:
a = 62°Step-by-step explanation:
a = 360° - (243° + 55°) = 360° - 298° = 62°what is the equation of the line that passes through the point (3,-8)and has a slope of 0
Answer:
y = -8
Step-by-step explanation:
no slope so y is always the same, the y value is -8 so y = -8

determine the value of k if g(x)=4x-k is a tanget to f(x)=-x²+8x+20
Answer:
This seems to be incomplete because we do not know where g(x) must be tangent to f(x). So i will assume that we want g(x) to be a tangent to f(x) in the point x0.
We know that for a function f(x), f'(x) is the tangent function in at the point x.
Where f'(x) = df(x)/dx
So we can find a value of k that is equal (for some value of x) to the first derivative of f(x).
g(x) = 4*x - k
f(x) = -x^2 + 8*x + 20
f'(x) = -2*x + 8
Now we want to find a value of k such that:
4*x0 - k = -2*x0 + 8
4*x0 - k = -2*x0 + 8
4*x0 + 2*x0 - 8 = k
6*x0 - 8 = k
Then if we want g(x) to be a tangent to f(x) = -x²+8x+20 in the point x0, we must have k = 6*x0 - 8

Answer:
6. C multiply the first equation by -7 ...
7. A parallel lines
Step-by-step explanation:
6. The idea of elimination is to create equations that have opposite coefficients for one of the variables. In this set of equations, there are two simple ways to achieve that.
On is to multiply the second equation by -2 (so x-coefficients are 4 in the first equation and -4 in the second equation).
The other is to multiply the first equation by -7 (so y-coefficients are -7 in the first equation and +7 in the second equation).
This latter method is described in answer choice C.
__
7. Equations are more easily compared if they are in the same form. Here, "standard form" is nice. To put the second equation in standard form, we must remove a factor of 3 from all of the numbers:
3(2x) +3(y) = 3(4)
2x +y = 4
We see that this differs from the first equation only in that it has a different right-side constant. That means it describes a parallel line.
in this figure prove that cd//ef
Answer:
1) 36 + 50 = 86 : Addition property of equality
2) m<D = m<ADB : If two angles have the same measure, then they are equal.
3) <D congruent to <ADB : if two angle are equal, then they are congruent.
4) <D, <ADB are alternate interior angles: assumed from diagram
5) CD // AB : if alternate interior angles are congruent, then the 2 lines cut by a transversal are //.
6) 130 + 50 = 180 : addition property of equality
7) m<E, m<BAE are supplements : if the sum of two angles equal to 180, then they are supplements.
8) <E, <BAE are same-side interior angles : assumed from diagram
9) EF // AB : if same-side interior angles are supplements, then the 2 lines cut by a transversal are //.
10) CD // EF : if two lines are // to the same line, then they are //.

. Jacob and Sadie each got ahead on their skills practices. Jacob completed twelve fewer problems than twice the number Sadie completed. They completed a total of 127 problems. Which system of equations models this situation if Jacob completed j problems & Sadie completed s problems? A) j + s = 127
Answer:
2s-12=j
S+J=127
Step-by-step explanation:
ok so firstly you are going to have 2 problems. Jacob has 12 fewer than 2x Sadie's so it will look like this, 2s-12=j
. 2x Sadie's minus 12 will give you Jacobs. and then it tells you that together they have 127 completed so S+J=127
hope this helps!!
