Answers

Answer:

Step-by-step explanation:

=(2(3x+4)(x−1))(x+−3)

=(2(3x+4)(x−1))(x)+(2(3x+4)(x−1))(−3)

=6x3+2x2−8x−18x2−6x+24

After solving the given expression, the equivalent expression will be equal to 6x³ - 16x² - 14x + 24.

What are arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the given expression in the question,

2(3x+4) (x−1) (x−3)

three orders are placed at a pizza shop.
two small pizzas, a liter of soda, and a salad costs $14.
one small pizza, a liter of soda, and three salads costs $15.
three small pizzas, a liter of soda, and two salads costs $22.
how much does each item cost?

Answers

Given:

Two small pizzas, a liter of soda, and a salad costs $14.

One small pizza, a liter of soda, and three salads costs $15.

Three small pizzas, a liter of soda, and two salads costs $22.

To find:

The cost of each item.

Solution:

Let x be the cost of a small pizza.

y be the cost of a liter of soda

z be the cost of a salad.

According to the question, two small pizzas, a liter of soda, and a salad costs $14.

[tex]2x+y+z=14[/tex] ...(i)

One small pizza, a liter of soda, and three salads costs $15.

[tex]x+y+3z=15[/tex] ...(ii)

Three small pizzas, a liter of soda, and two salads costs $22.

[tex]3x+y+2z=22[/tex] ...(iii)

From (i), we get

[tex]z=14-2x-y[/tex] ...(iv)

Putting [tex]z=14-2x-y[/tex] in (ii), we get

[tex]x+y+3(14-2x-y)=15[/tex]

[tex]x+y+42-6x-3y=15[/tex]

[tex]-5x-2y=15-42[/tex]

[tex]-(5x+2y)=-27[/tex]

[tex]5x+2y=27[/tex] ...(v)

Putting [tex]z=14-2x-y[/tex] in (iii), we get

[tex]3x+y+2(14-2x-y)=22[/tex]

[tex]3x+y+28-4x-2y=22[/tex]

[tex]-x-y=22-28[/tex]

[tex]-(x+y)=-6[/tex]

[tex]x+y=6[/tex]

Multiply both sides by 2.

[tex]2x+2y=12[/tex] ..(vi)

Subtracting (vi) from (v), we get

[tex]5x+2y-2x-2y=27-12[/tex]

[tex]3x=15[/tex]

[tex]x=5[/tex]

Putting x=5 in (vi), we get

[tex]2(5)+2y=12[/tex]

[tex]10+2y=12[/tex]

[tex]2y=12-10[/tex]

[tex]2y=2[/tex]

[tex]y=1[/tex]

Putting x=5 and y=1 in (iv), we get

[tex]z=14-2(5)-(1)[/tex]

[tex]z=14-10-1[/tex]

[tex]z=3[/tex]

So, [tex]x=5,y=1,z=3[/tex].

Therefore, the cost of a pizza is $5, cost of a liter of soda is $1 and cost of salad is $3.

Solve the equation.
8 (2-6v) +19=-61

Answers

Answer:

v = 2

Explanation:

8(2 − 6v) + 19 = −61

[ Simplify both sides of the equation ]

8(2 − 6v) + 19 = −61

(8)(2) + (8)(−6v) + 19 = −61 (Distribute)

16 + −48v + 19 = −61

(−48v) + (16 + 19) = −61 (Combine Like Terms)

−48v + 35 = −61

[ Subtract 35 from both sides ]

−48v + 35 − 35 = −61 − 35

−48v = −96

[ Divide both sides by -48 ]

−48v / -48 = −96 / -48

v = 2

(7y2 + x2 = 64
10.
x+y = 4

Answers

Answer:

Step-by-step explanation:

7[tex]y^{2}[/tex]+[tex]x^{2}[/tex]=64x+y=4

First, we isolate the variable on the second equation so that we can have an x solution to plug in:

x=-y+4

Now, we plug this in to the first equation:

[tex]7(-y+4)^{2} +(-y+4)^{2} =64[/tex]

We can now put the 7 into the parentheses and then square root the equation:

[tex]\sqrt{(-7y+28)^{2}} +\sqrt{(-y+4)^{2}} =\sqrt{64}\\-7y+28-y+4=8\\-8y=40\\y=-40[/tex]

We then plug this in to the original equation to find x

[tex]x+-40=4\\x=-36[/tex]

This means y=-40 and x=-36. I believe that's what you were asking. Let me know if it is something else

True or False: The Commutative Property of Addition states that for all expressions a and b , ab = ba.

Answers

According to the Commutative Property of Addition, ab = ba for all expressions a and b: FALSE

What is the Commutative Property of Addition?According to the commutative property of addition, altering the order of addends has no impact on the sum. Here's an illustration: 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+4. The addition and multiplication arithmetic operations are covered by the commutative property. This implies that the outcome of adding or multiplying two numbers remains unchanged if the order or position of the numbers is changed. For instance, 4 + 5 equals 9, and 5 + 4 equals 9.

According to the Commutative Property of Addition, rearranging the addends has no impact on the sum.

a+b=b+a

Therefore, the statement "according to the Commutative Property of Addition, ab = ba for all expressions a and b" is FALSE
