im confused can someone help me

Given:

The area model.

To find:

The area as a sum and area as a product.

Solution:

The four terms of the area model are [tex]2x^2,10x, 3x, 15[/tex].

The area as a sum is the sum of all the terms of given area model.

Area as a sum = [tex]2x^2+10x+3x+15[/tex]

                        = [tex]2x^2+13x+15[/tex]

The area as a product is the factor form of sum of all the terms of given area model.

Area as a product = [tex]2x^2+10x+3x+15[/tex]

                        = [tex]2x(x+5)+3(x+5)[/tex]

                        = [tex](x+5)(2x+3)[/tex]

Therefore, the area as a sum is [tex]2x^2+13x+15[/tex] and the area as a product is [tex](x+5)(2x+3)[/tex].

Answer:

1961.6 as decimal

Step-by-step explanation:

I divided it

Answer:

8%

Step-by-step explanation:

Solving our equation

r = 1600 / ( 2000 × 10 ) = 0.08

r = 0.08

converting r decimal to a percentage

R = 0.08 * 100 = 8%/year

The interest rate required to

accumulate simple interest of $ 1,600.00

from a principal of $ 2,000.00

over 10 years is 8% per year.

Answer:

shift the graph horizontally to the right for 3 units and then shift vertically up 2 units

Step-by-step explanation:

f(x) = x³  vs f(x-3)+2

f(x-3) will shift the graph horizontally to the right for 3 units

+2: will shift vertically up 2 units

Answer:

Answer:

18 trucks of delivery

Step-by-step explanation:

Total pallets of concrete blocks ordered = 252 pallets

If each truck can carry 14pallets, then;

1 truck = 14pallets

To determine the number of delivery truck 252pallets can carry, we can express this as:

x truck = 252pallets

Divide both expressions

1/x = 14/252

Cross multiply

14x = 1×252

14x = 252

x = 252/14

x = 18

Hence the manger should expect 1 18 trucks of delivery

Answer:

50.528º

Step-by-step explanation:

tanA = BC/BA

tanA = 17/14

A = 50.528º

Answer:

Step-by-step explanation:

Step One

Find the supplement of both exterior angles. They both have angles that add with them to make 180 degrees.

x + 105 = 180            Subtract 105 from both sides

x = 180 - 105

x = 75

y + 148 = 180            Subtract 148 from both sides

y = 180 - 148  

y = 32

Step Two

There are two ways to conclude the problem. You could find the value of the 3rd angle of the triangle, or you could notice that x is going to be the sum of the 2 angles you just found. These two angles are called the remote interior angle.

Method One

x = 32 + 75

x = 107

Method Two

32 + 75 + y = 180

107 + y = 180

y = 180 - 107

y = 73

The sum of x + 73 = 180

x = 180 - 73

x = 107

Answer:

6%

Step-by-step explanation:I

I'm going to assume that the interest is compoudning anually and there was only one payment

we know that

FV=PV(1+i)^N

which means taht

25560=18000(1+i)^6

Solve for i and get .06 or 6%

Answer:

Assuming the numerator was 1.

[tex](6\sqrt{7}+1)/251[/tex]

Step-by-step explanation:

Assuming the numerator was 1.

[tex]1/(6\sqrt{7} -1)\\ (6\sqrt{7}+1)/((6\sqrt{7} - 1)(6\sqrt{7} + 1))\\ (6\sqrt{7}+1)/((6\sqrt{7})^2 + 6\sqrt{7} - 7\sqrt{7} - 1)\\(6\sqrt{7}+1)/((6\sqrt{7})^2 - 1)\\(6\sqrt{7}+1)/((36*7 - 1)\\(6\sqrt{7}+1)/251[/tex]

Answer:

slope is m= y_2-y_1/x_2-x_1 and the y-intercept is where the line crosses over the x-axis

Step-by-step explanation:

fill in the points and do the equation m= rise(y points)/ run(x points)

m=slope

(x_1, y_1) =coordinates of first point in the line

(x_2, y_2)=coordinates of second point in the line

Answer:

Step-by-step explanation:

y ∝  x

y= k*x

As given y =-16, x=4 putt in above formula to get value of K

k = -16/4  = -4

Hence also given that ,

y =20

k = -4

x= ?

x= y/k    (using formula)

x =20 / -4

x = -5

Answer: y = 31

Step-by-step explanation: all you need to do is plug in the x

since x = -21 we can put: -21 + y = 10

now we add 21 to both sides giving us: y = 31

Answer:

(-21,22)

Step-by-step explanation:

x+y=10

x=-21

subtitue the x value

-21+y=2

solve for y

y=22

Then write your answer by ordered pair

(-21,22)

Answer:

y = -25x + 170

Step-by-step explanation:

For the graph equation y = ax + b, we have to find a and b.

Pick two points that are on the grid for best accuracy.

e.g., (2,120) and (6,20)

Then a = (20-120)/(6-2) = -25

b is the y coordinate of the line with the y axis: 170

So the formula is:

y = -25x + 170

Answer:

standard form: ax² + bx + c = 0

x² - 1 = -7x

x² + 7x - 1 = 0

Answer:

[tex]y = x^{2} + 3x + 1[/tex]

Step-by-step explanation:

Perimeter equals the sum of the lengths of the sides.

Let y = the length of the fourth side

[tex]4x^{2} + 3x - 4 = x^{2} + 2x + 15 + x^{2} -x - 10 + x^{2} - x - 10 + y[/tex]

[tex]4x^{2} + 3x - 4 = 3x^{2} - 5 + y[/tex]

[tex]x^{2} + 3x + 1 = y[/tex]
