[tex] \sf{( {x}^{2} + 3x - 7) - (3 {x}^{2} - 5x + 3)}[/tex]

When there is a ( - ) in front of an expression in parentheses, change the sign of each term in the expression. Also, remove the parentheses

⇒[tex] \sf{ {x}^{2} + 3x - 7 - 3 {x}^{2} + 5x - 3}[/tex]

Collect like terms

⇒[tex] \sf{ {x}^{2} - 3 {x}^{2} + 3x + 5x - 7 - 3}[/tex]

⇒[tex] \sf{ - 2 {x}^{2} + 8x - 10}[/tex]

Answer:

2

Step-by-step explanation:

Simplify the following:

(-(2 + 2/3))/(-(1 + 1/3))

(-(2 + 2/3))/(-(1 + 1/3)) = (-1)/(-1)×(2 + 2/3)/(1 + 1/3) = (2 + 2/3)/(1 + 1/3):

(2 + 2/3)/(1 + 1/3)

Put 1 + 1/3 over the common denominator 3. 1 + 1/3 = 3/3 + 1/3:

(2 + 2/3)/(3/3 + 1/3)

3/3 + 1/3 = (3 + 1)/3:

(2 + 2/3)/((3 + 1)/3)

3 + 1 = 4:

(2 + 2/3)/(4/3)

Put 2 + 2/3 over the common denominator 3. 2 + 2/3 = (3×2)/3 + 2/3:

((3×2)/3 + 2/3)/(4/3)

3×2 = 6:

(6/3 + 2/3)/(4/3)

6/3 + 2/3 = (6 + 2)/3:

((6 + 2)/3)/(4/3)

6 + 2 = 8:

(8/3)/(4/3)

Multiply the numerator by the reciprocal of the denominator, (8/3)/(4/3) = 8/3×3/4:

(8×3)/(3×4)

(8×3)/(3×4) = 3/3×8/4 = 8/4:

8/4

The gcd of 8 and 4 is 4, so 8/4 = (4×2)/(4×1) = 4/4×2 = 2:

Answer:

[tex](x-5)(x+8)=x^2+3x-40[/tex]

Step-by-step explanation:

So we have the expression:

[tex](x-5)(x+8)[/tex]

To multiply, distribute the left to the terms on the right:

[tex]=(x-5)(x)+(x-5)(8)[/tex]

Distribute:

[tex]=(x^2-5x)+(8x-40)[/tex]

Combine like terms:

[tex]=(x^2)+(-5x+8x)+(-40)[/tex]

Simplify:

[tex]=x^2+3x-40[/tex]

Therefore:

[tex](x-5)(x+8)=x^2+3x-40[/tex]

Step-by-step explanation:

x^2 + 8x - 5x - 40

Answer:

each month 3 employees were laid off.

Step-by-step explanation:

the company started with 65 employees 12 months ago, and now there are 29. 65 - 29 = 36. In 12 months, 36 employees were laid off. 36 employees divided by 12 months = 3 employees per month.

Answer:  [tex]-56\cdot 25\cdot 4 = -5600[/tex] .

Step-by-step explanation:

Associative property of multiplication : We can group numbers to multiply in any order like

[tex]p\times (q \times r) = (p\times q )\times r = p\times q\times r[/tex], where p , q and r can be any expression.

The given expression : [tex]-56\cdot 25\cdot 4[/tex]

By using associative property of multiplication, we have

[tex]-56\cdot(25\cdot 4)\\\\= -56\cdot 100\\\\=-5600[/tex]

Hence, [tex]-56\cdot 25\cdot 4 = -5600[/tex] .

Answer:

Step-by-step explanation:

Given AC = 23, AB = 2x + 2 and BC = 3x+6 then using vector notation;

BA+AC = BC

Since BA = -AB

The equation becomes -AB+AC = BC

Substituting the given equations;

-(2x+2)+23 = 3x+6

open the parenthesis

-2x-2+23 = 3x+6

-2x+21 = 3x+6

collect the like terms

-2x-3x = 6 - 21

-5x = -15

Divide both sides by -5

-5x/-5 = -15/-5

x = 3

TO get BC, we will substitute x = 3 into the expression BC = 3x+6

BC = 3(5)+6

BC = 15+6

BC = 21

Hence the length of BC is 21 units

Answer:

34 5/8 inches

Step-by-step explanation:

Let the two strips be fabric A and fabric B

Fabric A= 14 3/4 inches

Fabric B = 20 7/8 inches

To form one length, the strips are sown together using 1/2 inch

Length after sewing=

Fabric A - 1/2 inch

= 14 3/4 inches - 1/2 inch

= 59/4 - 1/2

= 59-2 /4

= 57/4 inches

Length after sewing=

Fabric B - 1/2 inch

= 20 7/8 inches - 1/2 inch

= 167/8 - 1/2

= 167-4 /8

= 163/8 inches

Final length of the fabric after two strips are sewn together

= 57/4 inches + 163/8 inches

= 114+163 /8

= 277/8

= 34 5/8 inches

Final length of the fabric after two strips are sewn together= 34 5/8 inches

Answer:

y = -|x-2| (*)

2 cases:

case 1: for x≥2 <=> |x-2| = x-2

(*) <=> y = - (x-2)

<=> y = -x+2

<=> x+y = 2

case 2: for x>2 <=> |x-2| = 2-x

(*) <=> y = -(2-x)

<=> y = x-2

<=> x-y = 2

since there are 2 variables but just one equation, we cannot find the exact values of x and y. Instead, we can find some kind of connection between them.

Answer:

Step-by-step explanation:

340-243 =97

97/6 = 16

16 weeks to lose 6 pounds per week.

Answer:

Let's think.

If we want the man to be in the best case scenario in which he loses the most pounds that his limit lets him, we should always make the man lose the highest he could go: 6 pounds.

This is just a simple multi step problem if you break it down.

If his goal is to get to 243 pounds, we firstly subtract 243 from 340 to see how much he needs to lose.

340 - 243 = 97

The man wants to lose 97 pounds.

Let's divide this number by 6 with remainder.

I'll let you think for a bit.

97 / 6 = 16 remainder 1.

This means that in 16 weeks, he needs to lose 6 pounds while on the 17th week, he needs to lose 1 pound.

I'm sorry if i misunderstood.

Good luck Mate :)

Answer:

14, 42

Step-by-step explanation:

Set A = {−7, −4, 2, 14, 21, 34, 42}

Set B = {even numbers}

Set C = {multiples of 7}

There is only one question asked

Which numbers in Set A are elements of both Set B and Set C,

We need it to be even and a multiple of 7

14 is even and a multiple of 7  and 42 is even and a multiple of 7

Answer:

[tex]\Huge \boxed{\mathrm{\{ 14, 42\} }}[/tex]

Step-by-step explanation:

[tex]\mathrm{Set \ A = \{-7, -4, 2, 14, 21, 34, 42\} }\\\\\\\mathrm{Set \ B = \{even \ numbers\} } \\\\\\\mathrm{Set \ C = \{multiples \ of \ 7\}}[/tex]

Whatever number is in Set A, it must also be in Set B and Set C.

The elements in Set A must be an even number and a multiple of 7.

Multiples of 7 from Set A are -7, 14, 21, 42.

The even numbers from these multiples of 7 are 14 and 42.
