find the square of the following number by using (a+b)2 or (a-b)2 .10001​

2(3b - 8) + 3b + 5 =

= 6b - 16 + 3b + 5 =

= 6b + 3b - 16 + 5 = 9b - 11 ← the end

Answer:

76

Step-by-step explanation:

let the number be x

Then 16 + x/-4 = -3, so

x/-4 = -16-3 = -19 (add -16 on both sides)

x = -4*-19 = 76 (multiply by -4 on both sides)

Answer:

(p - q)(2) = 5

Step-by-step explanation:

(p - q)(2)

= p(2) - q(2)

From the table for p(x)

when x = 2 , p(2) = 3

From the table for q(x)

when x = 2 , q(2) = - 2

Then

(p - q)(2) = 3 - (- 2) = 3 + 2 = 5

Answer: it’s 1 not 5 or -5

Step-by-step explanation:

Recall the following identities:

cos(4x) = cos⁴(x) - 6 cos²(x) sin²(x) + sin⁴(x)

cos(3x) = cos³(x) - 3 cos²(x) sin(x)

sin²(x) = 1 - cos²(x)

Then the equation

cos(4x) = cos²(3x) + sin²(x)

can be rewritten entirely in terms of cos(x) as

8 cos⁴(x) - 8 cos²(x) + 1 = 16 cos⁶(x) - 24 cos⁴(x) + 8 cos²(x) + 1

16 cos⁶(x) - 32 cos⁴(x) + 16 cos²(x) = 0

16 cos²(x) (cos²(x) - 1)² = 0

Now we can solve:

cos²(x) = 0   or   (cos²(x) - 1)² = 0

cos(x) = 0   or   cos²(x) - 1 = 0

cos(x) = 0   or   cos²(x)  = 1

cos(x) = 0   or   cos(x) = -1   or   cos(x) = 1

x = π/2 + 2nπ   or   x = -π/2 + 2nπ

…   or   x = π + 2nπ

…   or   x = 2nπ

where n is any integer.

Answer:  Your question is written f(x) = -2*(-3+3)+1.  I'll assume you need the answer for just the one value of x (-3)?  If so, f(-3) = 1.

Step-by-step explanation:  

f(x) = -2*(-3+3)+1

f(x) = -2*(0)+1

f(x) = 1

Other values x for the equation f(x) = -2*(x+3)+1:

-2 is -1

1  is -7

Answer:

6 cm

Step-by-step explanation:

Area = ½ × b × h

24 = ½ × 8 × h

24 = 4 × h

24/4 = h

6 = h

Answer:

62

Step-by-step explanation:

h(-3)= -3(3)^3+5(-3)

=81-15= 66

g(h(-3))= x-4 : substitute h(-3) in g(x)

=66-4

=62

Answer:

88.23

Step-by-step explanation:

The equation for the first plan is:

9 + 0.17x

The equation for the second plan is

24

Then you set the two equations equal to each other

9 + 0.17x = 24

Subtract on both sides

0.17x = 15

Divide

x = 88.23

Step-by-step explanation:

strange, because the way you typed it, it would be absolutely correct.

If a < b and if c is a positive number, then

a/c < b/c

Dividing each side of an inequality by a positive number does not change the direction of the inequality symbol.

that is one of the defined rules.

so, did you make a mistake with a sign ? maybe the division is meant to be by -3 ?

then indeed, suddenly

5 > 2

so, please check the problem definition precisely. if your correct answer is actually wrong, then the original problem must be different than what you typed here.

The value of the inequality after dividing both sides by 3 is - 5 < - 2

Given the inequality : - 15 < - 6

Dividing both sides of the inequality by 3 :

THE inequality becomes :

-15/3 < - 6/3

-5 < - 2

Hence, the result after dividing both sides of the inequality by 3 is - 5<-2

Step-by-step explanation:

Answer:

58 = 3.5x + 2

Step-by-step explanation:

Since $3.50 is charged for every mile, we multiply x by 3.5 like this: 3.5x

$2 is already added on as a free so + 2

$58 is the total amount of money for all of the charges including the per mile and pick-up fee.

This was we can solve for the number of miles, x

58 = 3.5x + 2

- 2            - 2

56 = 3.5x

56/3.5 = 3.5x/3.5

x = 16

Step-by-step explanation:

Answer:

x=6

AD=x+18

=6+18

=24 (the final answer)

Answer:

x = 6

AD = 24

Step-by-step explanation:

To find the value of x and AD

We know that the opposite sides of parallelogram are equal

so

AD = BC

3x + 6 = x + 18

3x - x = 18 - 6

2x = 12

x = 12/2

x = 6

now we need to find AD

AD =3x + 6

instead of x we have to put 6

AD =  3 (6) +6

     = 18 +6

     = 24

AD = 24

To work this out you need the denominator to be the same. So, you multiply 2/5 by 2 which equals 4/10.

4/10 + 4/10 = 8/10
