Answer:

96 cm

Step-by-step explanation:

for the triangles do 5×6×4

then divide it by 2 to get 60 then do 6×6 for the square to get 36. Add 36 and 60 together to get 96.

The function gets shifted towards the left then the value of h must be negative. The correct option is B.

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.

Answer:

16 rows

Step-by-step explanation

48x10=480, then divide 480 by 30. 480÷30=16. So, there will be 16 rows.

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

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:

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]

Answer:

x = -3 y = -8 (-3,-8)

Step-by-step explanation:

first you would subsitute the y with (2x-2) in -3x+4y=-23 as y=2x-2

giving you-3x+4(2x-2)=-23

next you distribute the 4 to (2x-2) leaving you with -3x+8x-8=-23

then add -3x+8x to get 5x, having 5x-8=-23

add 8 to both sides canceling out 8 on one side and adding 8 to the other leaving you with 5x=-15 then you divide 5 from 5x to both sides leaving you with x = -3

next is y since you have x you would substitute the x in y=2x-2 with -3 getting y=2(-3)-2 then you multiply the 2 and -3 so you have y=-6-2 then you subtract those getting y = -8

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
