Answer:

For a polynomial of the form ax²+bx+c, rewrite the middle term as a sum of two terms whose product is  a⋅c = 8⋅ −3=−24 and whose sum is b=−2.

8t²+4t−6t−3

Factor out the greatest common factor from each group.

4t(2t+1)−3(2t+1)

Factor the polynomial by factoring out the greatest common factor, 2t+1.

(2t+1)(4t−3)

Answer:

The perimeter of a rectangle is 30 meters. The length of the rectangles is 3 meters more than twice the width. Find the dimensions of the rectangle.

Step-by-step explanation:

Equation for Perimeter of a rectangle: Perimeter = 2W + 2L

Defining the variables, let

Width = x

Length = 2x+3 (3 more than twice the width)

Plugging everything into the equation

30= 2(x) + 2(2x+3) using the distributive property,

30=2x+4x+6 combining like terms

30=6x+6 subtracting 6 from both sides,

24=6x divide both sides by 6

4=x This means that the width is 4 m

To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved for

L=2(4)+3

L=8+3 = 11 m

So the dimensions of the rectangle are width is 4 m and length is 11 m

Step-by-step explanation:

f(x)=2x and g(x)=x2+3, find (g ∘ f)(−3)

f(x)= 2(-3)= -6

g(x)= (-3)(2) +3= -6+3= -3

(g ∘ f) = -6 x -3= 18

Step-by-step explanation:

The scale factor is 3 and the value of the unknown variable of the larger floor is 36 ft and this can be determined by using the given data.

Given :

a) Let the scale factor be 'y'. So, the value of 'y' can be calculated as:

[tex]\begin{aligned}\\24 &= y \times 8\\y &= 3\\\end{aligned}[/tex]

So, the scale factor is 3.

b) The value of the unknown variable of the larger floor is calculated as:

[tex]\begin{aligned} \\12\times y &= x\\12\times 3& = x\\x&= 36\\\end{aligned}[/tex]

So, the value of the unknown variable of the larger floor is 36 ft.

Answer: 18oz

Step-by-step explanation:

Answer:

7.2 inches

Step-by-step explanation:

First, we find the length of the legs, which are the sides that are parallel to the x- and y-axis.

The leg parallel to the x-axis is 6 inches long.

The leg parallel to the y-axis is 4 inches long.

After finding the length of both legs, we can use the Pythagorean Theorem to find the length of the hypotenuse: a² + b² = c²

a and b being the legs, and c being the hypotenuse

6² + 4² = c²

36 + 16 = c²

52 = c²

√52 = c

c ≈ 7.2 inches

Answer:

1 1/2 miles (one and a half miles)

Step-by-step explanation:

Answer:

Since she started with $80 and ended with with $35,24, we can find the total amount she spent by subtracting these amounts:

$80 - $35.24 = $44.76

This means that she spent $44.76 on coffee. If each pound cost $7.46, we can divide $44.76 by $7.46 to see how many pounds she bought (ignoring tax):

44.76 / 7.46 = 6 pounds of coffee purchased

Answer:

let KL be the string PL be perpendicular distance between them. and KL be height of kite flying.

in right angled triangle

relationship between perpendicular and hypotenuse is given by sin angle

sin 31°=p/h

h=65/sin31

KP=126.2m

the length of string is 126.2m

Answer:

127.45 m

Step-by-step explanation:

Given :-

To Find :-

Solution :-

Here we need to find out the length of the string here if we imagine a right angle triangle in which the height of the kite will be the perpendicular of the triangle and the length of the string will be the hypotenuse of triangle .

And the angle between the the string and the ground will be 31°.

Here we can use ratio of sine as ,

> sin∅ = p/h

> sin 31° = 65m/ h

> h = 65m/sin 31°

> h = 65m/0.51

> h = 127 .45 m

Answer:

12/27

Step-by-step explanation:

You have a bag that contains 6 red marbles and 3 blue marbles. You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.

Let the total number of marbles = 6 red marble + 3 blue marbles = 9 marbles

You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.

Assume all you picked is red( without replacement)

= 6/9 × 5/9

= 30/81

= 10/27

Assume all you picked is blue( without replacement)

= 3/9 × 2/9

= 6/81

= 2/27

The probability of the events is calculated as:

All red or All blue

= 10/27 + 2/27

= 12/27
