Find the equivalent expressions for (x + 7)(x + 1).
x(x + 7+8)
(x +4)^2 - 9
x^2+ 8x + 7
x^2+ 7x + 8
(x+ 4)^2 +9
x(x + 8) +7

Answer:

C. x = 12

Step-by-step explanation:

The equation simplifies to [tex]\frac{5}{6} x + 4 = x + 2[/tex]. This can further simplify to [tex]-\frac{1}{6}x = -2[/tex]. Divide both sides by [tex]-\frac{1}{6}[/tex] to get [tex]x = 12[/tex].

Answer:

3/8 room

Step-by-step explanation:

Given data

We are told that 2 rolls of wire are needed to wire 1 room

Hence if 1 room needs 2 rolls

               x rooms will need 3/4 rolls

cross multiply we have

2x= 3/4

Multiply  both sides by 1/2

x= 3/4*1/2

x= 3/8 room

Answer:

A.16.5 if that’s incorrect try b.33

Step-by-step explanation:

The formula is: A = B * H where B is the base, H is the height, and * means multiply.

it may be wrong I’m not sure but  30 * 11 is 330 divded by 2 is 16.5

Answer:

Perimeter of i - 22CM

Area of i - 13CM^2

Perimeter of ii -38CM

Area of ii -66CM^2

Perimeter of iii -30CM

Area of iii- 42CM^2

Perimeter of iv - 50CM

Area of iv- 126CM^2

Step-by-step explanation:

SHAPE I:

PERIMETER = S + S + S + S + S +S

= 7 + 1 + 5 +3 +4 +2

= 22CM

AREA = Part a - 4 * 2 = 8cm^2 part B - 5 *1 = 5cm^2

Total = 8 + 5 = 13cm^2

SHAPE II:

PERIMETER = S + S + S + S + S +S

= 4 + 4 +5 + 6 + 9 + 10

= 38 CM

AREA = Part a - 5 * 10 = 50 cm^2 part B - 4 *4 =16 cm^2

Total = 50+16 =66 cm^2

SHAPE III:

PERIMETER = S + S + S + S + S +S

= 9 + 2 + 3 + 4 + 6 + 6

= 30CM

AREA = Part a - 6 * 6 = 42cm^2 part B - 3 * 2= 6cm^2

Total = 36 + 6 =42 cm^2

SHAPE IV:

PERIMETER = S + S + S + S + S +S

= 9 + 10 + 4 + 6 + 6 + 15

= 50 CM

AREA = Part a -15 * 6 = 90 cm^2 part B - 9 *4 = 36cm^2

Total = 90 + 36 = 126cm^2

Answer:

45/8, or 5.625

Step-by-step explanation:

20/4 is simplified to 5/1.

5/1 divided by 8/9

5/1 * 9/8

45/8

simplified to 5.625

Answer:

45/8 or 5 5/6.

Step-by-step explanation:

20/4 / 8/9            We invert the second fraction and multiply:

= 20/4 * 9/8

= 180 / 32

= 45/8

= 5 5/8.

Answer:

19% alcohol solution = 65 ounces

37% alcohol solution = 25 ounces

Step-by-step explanation:

Let

19% alcohol solution = x

37% alcohol solution = y

x + y = 90 (1)

0.19x + 0.37y = 90*0.24

0.19x + 0.37y = 21.60 (2)

from (1)

x = 90 - y

Substitute into (2)

0.19x + 0.37y = 21.60

0.19(90-y) + 0.37y = 21.60

17.1 - 0.19y + 0.37y = 21.60

- 0.19y + 0.37y = 21.60 - 17.1

0.18y = 4.5

y = 4.5/0.18

y = 25 ounces

x + y = 90 (1)

x + 25 = 90

x = 90 - 25

x = 65 ounces

Answer: 4/15 of the movie

Step-by-step explanation:

In the morning, Charlie watched ¹/₃ of a movie. He then watched some more at night.

At the end of the day, he still had ²/₅ of the movie to watch.

The proportions of an item must always add up to one. This means that if you added the 1/3 to the 2/5 and then to the fraction Charlie watch at night, they should add up to one.

¹/₃ + ²/₅ + x = 1

x = 1 - ¹/₃ - ²/₅

[tex]x = \frac{15 - 5 - 6 }{15} \\\\x = \frac{4}{15}[/tex]

Answer:

Answer: We can conclude that f(x) and g(x) are not inverses.

Step-by-step explanation:

If we have two functions:

f(x) and g(x)

These functions are inverses if:

f( g(x) ) = x

g( f(x) ) = x

In this case, we have:

f(x) = 12*x - 12

g(x) = (1/12)*x - 1

Now we need to check the compositions:

f( g(x) ) = 12*g(x) - 12 = 12*( (1/12)*x - 1) - 12 = (x - 12) - 12 = x - 24

and:

g( f(x)) = (1/12)*f(x) - 1 = (1/12)*(12*x - 12) - 1 = 12*x/12 - 12/12 - 1 = x - 1 - 1 = x - 2

In both cases, we can see that:

f( g(x) ) ≠ x

and:

g( f(x) ) ≠ x

Then we can conclude that f(x) and g(x) are not inverses functions.

Answer:

x = -9

Step-by-step explanation:

Plug in -5 to P then simplify the expression.

-5 = x/3 - 2

-3 = x/3

-9 = x

Answer:

I think X= -9

Step-by-step explanation:

Sub in -5 for p

-5=x/3 - 2

then add the -2

-3 =x/3

then multiple the 3

and you get -9

Answer:

[tex]25+3d=135.97[/tex]

Step-by-step explanation:

Number of pairs of socks = 10

Cost of each pair of socks = $2.50

Cost of 10 pairs of socks = 10 × 2.50 = $25

Number of pairs of shoes = 3

Cost of each pair of shoes = $d

Cost of d pair of shoes = $3d

Therefore,

[tex]25+3d=135.97[/tex]

So,

Equation is [tex]25+3d=135.97[/tex]

Answer:

15:15

Step-by-step explanation:

The time he would get to salt lake is the sum of all the times

8: 30 + 45 min + 50 min + 5:10

to find the time, add only the minutes : 30 + 45 + 50 + 10 = 135 minutes

Remember 60 mins = 1 hour

so 135 mins = 2 hours 15 minutes

Now add the hours

8 + 5 = 13 hours

13 hours + 2 hours 15 minutes = 15:15

Answer:

Number no. of times

80 occurs 5 times (most of the times) so, 80 will be the mean.

The simplified expression 1/3 * 1/3 * 1/3 as exponents is 1/3³

From the question, we have the following parameters that can be used in our computation:

1/3 * 1/3 * 1/3

Express as equation

Result = 1/3 * 1/3 * 1/3

Apply the law of indices

So, we have the following representation

1/3 * 1/3 * 1/3 = 1/3¹⁺¹⁺¹

Evaluate the sum

1/3 * 1/3 * 1/3 = 1/3³

Using the above as a guide, we have the following:

The expression cannot be further simplified

Hence, the simplified expression is 1/3³
