Answer 1

Answer:

[tex]-a^2+ab[/tex]

Step-by-step explanation:

So the sentence can be written like this:

[tex]((a^2-b^2)+(a^2+ab+3b^2))-((a^2-2ab+b^2)+(2a^2+2ab+b^2))[/tex]

Now you can combine like terms in the first part of the equation and the second part:

[tex]((a^2+a^2)+ab+(-b^2+3b^2))-((a^2+2a^2)+(-2ab+2ab)+(b^2+b^2))[/tex]

Which leaves you with:

[tex](2a^2+ab+2b^2)-(3a^2+2b^2)[/tex]

Now distribute the negative to the second part of the equation:

[tex]2a^2 + ab + 2b^2-3a^2-2b^2[/tex]

Combine like terms again:

[tex](2a^2-3a^2)+ab+(2b^2-2b^2)[/tex]

Which becomes:

[tex]-a^2+ab[/tex]

Answer 2

Answer:

- a² + ab

Step-by-step explanation:

summing the first 2 expressions

a² - 2ab + b² + 2a² + 2ab + b² ← collect like terms

= 3a² + 2b² → (1)

summing the next 2 expressions

a² - b² + a² + ab + 3b² ← collect like terms

= 2a² + ab + 2b² → (2)

Subtracting (1) from (2)

2a² + ab + 2b² - (3a² + 2b²) ← distribute parenthesis by - 1

= 2a² + ab + 2b² - 3a² - 2b² ← collect like terms

= - a² + ab

TACOS Orlando spent $18 at a taco truck. He ordered 4 tacos. Write and solve an equation to
find the cost of each taco.

Answers

Answer:

$4.5 for one taco

Step-by-step explanation:

18 divided by 4

The division is a process of splitting a specific amount into equal parts.

The equation to find the cost of each taco truck is 4x = 18.

The cost of each taco truck is $4.5.

What is division?

The division is a process of splitting a specific amount into equal parts.

Example:

5 apples cost $60.

Cost of each apple = 60/5 = $12.

We have,

Total amount spend = $18

Number of taco trucks where $18 was spent = 4

Let the cost of each taco truck = x

The equation to find the cost of each taco truck can be written as:

4x = 18

We need to find x.

x = 18/4

x = $4.5

Thus the cost of each taco truck is $4.5.

Answers

Answer:

x=-9/28

Step-by-step explanation:

-4(-6x-3)+4x=3

24x+12+4x=3

28x+12=3

28x=-9

x=-9/28

Answer:

x = -9/28

Step-by-step explanation:

-4(-6x - 3) + 4x = 3=> 24x + 12 + 4x = 3=> 28x + 12 = 3=> 28x = 3 - 12=> 28x = -9=> x = -9/28

Therefore, the solution is 'x = -9/28'.

The diameter of a circle is 14 in. Find its area in terms of
π
π.

Answers

Answer:

49π in²

Step-by-step explanation:

Step 1: Find the radius.

To find radius given diameter, just divide the diameter by 2: [tex]\frac{14}{2}[/tex] 14/2 = 7, so the radius is 7.

Step 2: Apply area of circle formula.

The formula to find the area of a circle is πr², where r = radius.Now, plug in the value of r: π(11)².

Step 3: Simplify.

π(11)²π(121)121π

Since we're finding the area in terms of pi, we don't have to multiply 121 by pi, so the answer is 49π in².

An alternating current i in amperes in a certain circuit can be found after t seconds using i= 3 (sin 150)t , where 150 is a degree measure. Rewrite the formula in terms of sum of two angle measures.
Group of answer choices

a 3[sin (130 + 15)] t

b 3[sin (45 + 45)] t

c 3[sin (180 - 45)] t

d 3[sin (90 + 60)] t

Answers

The formula in terms of sum of two angle measures is c 3[sin(90 + 60)]t

Since the alternating current i in amperes after t seconds is i = 3(sin150)t.

We want to write 150 as the sum of two angles measures.

So, 150 = 90 + 60.

So, the current i = 3(sin150)t

i = 3[sin(90 + 60)]t

So, the formula in terms of sum of two angle measures is c 3[sin(90 + 60)]t

explain why 256 + 4 is equivalent to (200 + 4) + (40+4) + (164)​

Answers

The expression 256 + 4 is equivalent to (200 + 4) + (40+4) + (16+4) according to distributive and commutative property of addition.

Given the expression 256 + 4. This can be solved using the partial sum expressed as:

256 + 4

256 + 4

= (200 + 40 + 16) + 4

According to the commutative property, A+B = B+A

The arrangement does not affect the result. Hence;

(200 + 40 + 16) + 4 = 4 +  (200 + 40 + 16)

Using the distributive law;

4 +(200 + 40 + 16) = (200 + 4) + (40 + 4) + (16 + 4)

Hence the expression 256 + 4 is equivalent to (200 + 4) + (40+4) + (16+4) according to distributive and commutative property of addition.

What error did she make? StartFraction part Over whole EndFraction = StartFraction 70 times 8,750 Over 100 times 8,750 EndFraction = StartFraction 612,500 Over 875,000 EndFraction.

Answers

Answer:

1,250,000

Step-by-step explanation:

875,000 sandals account for 70% of the total pairs sold.

875,000/7 = 125,000

125,000 accounts for 10%.

125,000 * 10 = 1,250,000.

1,250,000 accounts for 100%.

The company sells pairs of shoes in June is 612,500

In Emily's calculation the error she makes in the second last steps she forgets to write the term 70.

Given that,

Shiras Shoes sold 875,000 pairs of sandals in June, which was 70% of the total number of shoes sold.

We have to determine,

How many shoes did the company sell in June? Analyze Emily's calculations. What error did she make?

According to the question,

Shiras Shoes sold 875,000 pairs of sandals in June, which was 70% of the total number of shoes sold.

Then,

The shoes did the company sell in June is,

[tex]= \dfrac{70} {100}\times 875,000\\\\=8750 \times 70 \\\\= 612,500[/tex]

Hence, The company's sells pair of shoes in June is 612,500.
