Amal’s answer:

Which statement about Amal’s work is true?
Amal’s work is correct.
Amal’s work is incorrect the wrong divisor is on the right side of the division table.
Amal’s work is incorrect because it includes a positive two instead of negative two in the answer.
Amal’s work is incorrect because the like terms in the division table do not simplify to the original polynomial.

Product of two polynomials can be done by distribution of multiplication over addition. The product of  [tex]-2x(x^2 - 3)[/tex] is [tex]-2x^3 + 6x[/tex]

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The product result of the given expression is

[tex]-2x(x^2 - 3) = -2x^{1 + 2} + 6x = -2x^3 + 6x[/tex]

It is because when bases are same and there is multiplication, then powers add up, so we have: [tex]a^b \times a^c = a^{b+c}[/tex]

Thus,

The product of  [tex]-2x(x^2 - 3)[/tex] is [tex]-2x^3 + 6x[/tex]

The worth of the bond is $307.50.

The worth of the bond is the sum of the bond when it was bought and the interest earned on the bond.

Worth of the bond = interest rate + value when the bond was bought

Interest = 105% x $150

1.05 x $150 = $157.70

Worth of the bond = $157.70 + $150 = $307.50

Answer:

10.35

Step-by-step explanation:

The total billing amount is $31.05. The share of each person on the total billing amount is $10.35. Option C is the correct answer.

Given that the billing amount is $27.00. The additional tip is 15% of the billing amount. The final bill will be split into 3 persons.

The amount of tip is calculated as given below.

[tex]Tip = \dfrac { 15}{100} \times \$27.00[/tex]

[tex]Tip = \$4.05[/tex]

Now the total billing amount is the sum of the final bill and the amount of tip.

Total Bill = $27.00 + $4.05

Total Bill = $31.05

The share of each person on the total amount is given as,

Share = [tex]\dfrac {\$31.05}{3}[/tex]

Share = $10.35

Hence we can conclude that the share of each person on the total billing amount is $10.35. Option C is the correct answer.

Answer:

97°

Step-by-step explanation:

First, find the sum of the interior angles by using the following formula.

[tex]S = (n-2)180[/tex]

S is the sum and n is the number of sides

S = (5 - 2)180

S = (3)180

S = 540°

Next create an equation by adding all the interior angles together and setting the sum equal to the sum of the interior angles and solve for x, the missing angle.

72 + 136 + 127 + 108 + x = 540

443 + x = 540

443 - 443 + x = 540 - 443

x = 97°

Answer:

(3, 10)

Step-by-step explanation:

f(3) means substitute the value of x = 3 into f(x)

[tex]\implies f(3) = (3 \times 3) + 1 = 10[/tex]

Therefore, when x = 3, y = 10

So the ordered pair is (3, 10)

[tex]\\ \tt\longmapsto f(x)=3x+1[/tex]

[tex]\\ \tt\longmapsto f(3)=3(3)+1=9+1=10[/tex]

Pair is (3,10)

Answer:

AB = 7

Step-by-step explanation:

The y-coordinate of point A and B is the same.

Therefore, both points lie on the same horizontal line (y = 2).

So determine the distance between them, subtract the x-coordinate of B from the x-coordinate of A:

AB = 4 - -3 = 4 + 3 = 7

However, to calculate the distance between 2 points, regardless if the points are on a horizontal (or vertical) line, you can always use the distance between 2 points formula that is derived from Pythagoras' Theorem, as follows:

let [tex](x_1,y_1)[/tex] = point A (4, 2)

let [tex](x_2,y_2)[/tex] = point B (-3, 2)

using the distance between two points equation:

[tex]AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\implies AB=\sqrt{(-3-4)^2+(2-2)^2}[/tex]

[tex]\implies AB=\sqrt{(-7)^2+(0)^2}[/tex]

[tex]\implies AB=\sqrt{49}[/tex]

[tex]\implies AB=7[/tex]

   Angle at x is 75°

Step-by-step explanation:

Data :

  Angle at A = 65°

  Angle at B = 40°

According to  the porperty of triangle we know that total interior angle a triangle has is 180° irrespect of type or size

              A + B + C = 180

      65 + 40 + C = 180

Answer:

29 if I’m Wrong I’m sorry

Step-by-step explanation:

Volume of a figure is measure of the space it occupies. The volume of the larger rectangular prism is given as: Option C: 1620 cm³

If a rectangular prism has dimensions a unit, b unit, and c units, then its volume is given as

[tex]V = a \times b \times c \: \rm unit^3[/tex]

They are scaled. It means, if two figures are similar, then we can get one figure from another by multiplying some constant value(same for one pair of similar figure) to its dimensions.

For example,

if for given case, one rectangular prism has got dimensions a, b, and c centimetres, then

the second rectangular prism, which is similar, let the scale factor is 'd',t then second prism's dimensions will be a x d units, b x d units, and  c x d units.

For first prism(smaller), its one side is given to be 5 cm, let its other two sides be 'b' cm, and 'c' cm, then,

[tex]60 \: \rm cm^3 = 5\times b\times c \\\\b\times c = \dfrac{60}{5} = 12[/tex]

Now, the larger prism has 15 cm corresponding side, thus, scale factor was 3 (since 15 is 3 times 5).

Thus, its dimensions would be 15, 3 x b, 3 x c

Thus, its volume would be

[tex]15 \times 3 \times b \times 3 \times c = 135 \times b\times c = 135 \times 12 = 1620 \: \rm cm^3[/tex]

Thus,

The volume of the larger rectangular prism is given as: Option C: 1620 cm³

It's 360 feet (The person above)

Answer:

360 ft squared

Step-by-step explanation:

you have 3 (2 shapes but one is done twice)

2 rectangles and a larger rectangle

the 2 rectangles

3 is the width, and 15 is the length

15*3 = 45 * 2 (for the other one)

and you get 90ft squared

then you have the larger rectangle. it is 15 feet wide and 18 in length (15+3)

15*18 = 270

270 ft squared + 90 ft squared = 360 ft squared
