If k(x) = 5x – 6, which expression is equivalent to (k k)(4)?.
The expression 5(4) - 6 + 5(4) - 6 is equivalent to (k + k)(4) option fourth is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is:
If k(x) = 5x – 6, which expression is equivalent to (k + k)(4)?
5(4 + 4) – 6. 5(5(4) – 6) – 6. 54 – 6 + 54 – 6. 5(4) – 6 + 5(4) – 6Plug k = 4 in the function:
k(4) = 5(4) - 6
Now,
= (k + k)(4) or
= k(4) + k(4)
= 5(4) - 6 + 5(4) - 6
Thus, the expression 5(4) - 6 + 5(4) - 6 is equivalent to (k + k)(4) option fourth is correct.

30 chairs in it?
Answer:
16 rows
Step-by-step explanation
48x10=480, then divide 480 by 30. 480÷30=16. So, there will be 16 rows.
Brainly pls help me on this question.
Answer:
16ft
Step-by-step explanation:
The answer is 16ft because the area of a trapezoid is a + b/2 x h.
5 + 8/2 = 13/2 = 6.5
104/6.5 = 16
The height is 16ft.

Answer:
C (-5,[tex]\frac{8}{3}[/tex])
Step-by-step explanation:
I uses demos graphing calculator
First, found the slope using point (0,6) and (3,8)
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{8-6}{3-0}[/tex]
m = [tex]\frac{2}{3}[/tex]
m = slope
Now I will be able to form a linear equation:
y = mx + b (is our y-intercept, when x is 0) When x is 0, y is 6 (0,6)
y = [tex]\frac{2}{3}[/tex]x + 6
I graphed that on demos, and that's how I got my final answer.
I would attach the link to the graph, but brainly deleted my answer before. So, try to write that in to demos (y = [tex]\frac{2}{3}[/tex]x + 6) if you want to see the graph.
Hope that helps!

Answer:
the answer is 12.
Step-by-step explanation:
Hope this helps! :)
Answer:
20 ÷ [tex]\frac{5}{3}[/tex] = 12
Step-by-step explanation:
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
20 x 3 divided by 5 = 60\5
Thus, the answer to 20 divided by 5/3 in fraction form is:
[tex]\frac{60}{5} = 12[/tex]

During a football game, the parents of the football players sell pretzels and popcorn to raise money for new uniforms. They charge $2.50 for a bag of popcorn and $2 for a pretzel. The parents collect $336 in sales during the game. They sell twice as many bags of popcorn as pretzels. How many bags of popcorn and pretzels do they sell?
2.5x + 2y = 336
x = 2y
2 equations, 2 unknowns, solvable
3.5x = 336
7x = 672
x = 672 / 7
x = 96
96 / 2 = y
y = 48
they sold 96 popcorn bags and 48 pretzels

5x + 25 + x + 5 = 90
6x + 30 = 90
6x = 90 - 30
6x = 60
x = 10
Solution:
We can see that the 90° angle is divided into two angles. Thus, the sum of two angles must equal 90°.
=> 90 = 5x + 25 + x + 5Combine like terms:
=> 90 = x(5 + 1) + 5(5 + 1)=> 90 = x(6) + 5(6)=> 90 = 6x + 30Subtract 30 both sides:
=> 90 - 30 = 6x + 30 - 30=> 60 = 6xDivide 6 both sides:
=> 60 = 6x=> x = 60/6 = 10The value of x is 10.

The graph shows the function f(x) = |x – h| k. What is the value of h? h = –3. 5 h = –1. 5 h = 1. 5 h = 3. 5.
The function gets shifted towards the left then the value of h must be negative. The correct option is B.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
Given
The function is f(x) = |x – h| + k
We know that if we subtract h from the variable the function gets shifted towards the right but in the graph, the function gets shifted towards the left then the value of h must be negative.
We know the coordinate of the vertex is (-1.5, -3.5). Then abscissa will satisfy the |x - h|.
h = -1.5
Thus, option B is correct.

None of the triangles are similar. Some of the triangles are similar. Some of the triangles are similar. All of the triangles are similar. All of the triangles are similar. No conclusion can be drawn without knowing the measurements of the angles.
Answer:
(c) All of the triangles are similar
Step-by-step explanation:
All of the triangles are similar by the AA similarity postulate.

The figure shows a kite ABCD where AB = AD, BC = CD and the diagonals AC and BD intersect at E.
Find:
(I) ABD
(II) CBD
Answer:
ABD
Step-by-step explanation:
Mark brainliest today afternoon message was not going that account was deleted
this is my new account ha Aryan hu
From the kite ABCD, ∠ABD = 65° and ∠CBD = 46°
Properties of a kite:Pair of adjacent sides are equalOne pair of opposite angle is equalDiagonals are perpendicular to each otherThe longer diagonals bisect the other diagonal.∠ABC≅∠ADC
∠EDC = 180 - 90 - 44 (sum of angle in a triangle)
∠EDC = 46°
∠EDC ≅∠EBC
∠ADE = 180 - 25 - 90 (sum of angle in a triangle)
∠ADE = 65°
∠ADE ≅ ∠ABD(Base angle of isosceles triangle)
Therefore,
∠ABD = 65°
∠EDC ≅ ∠CBD (Base angle of isosceles triangle)
Therefore,
∠CBD = 46°

Help!! Its A Math Problem ! I am not sure how to solve it!! or show my work
Answer:
Step-by-step explanation:
#1.
2x² + 24x + 10 = 0
2(x² + 12x + 5) = 0
2[ x² + 2(6)x + 6² - 6² + 5 ] = 0
2[(x + 6)² - 31] = 0
2( x + 6 - √31 )( x + 6 + √31 ) = 0
[tex]x_{1}[/tex] = - 6 + √31
[tex]x_{2}[/tex] = - 6 - √31
#2.
f(x) = 3x² - 36x - 12
f(x) = 3( x² - 12x - 4 )
f(x) = 3 [ x² - 2(6)x + 6² - 6² - 4 ]
f(x) = 3 [( x - 6 )² - 40 ]
f(x) = 3( x - 6 )² - 120
