Answer:

first choice: ⁴√200 / 2

Step-by-step explanation:

√10 / ⁴√8 = ((√10)*(⁴√2)) / ((⁴√2³)*(⁴√2))  

                = (⁴√100 * ⁴√2) / (⁴√2⁴)

                = ⁴√200 / 2

Answer:

x = -4 3/16.

Step-by-step explanation:

First, convert -27/8 to a mixed number. -3 3/8.

So we can take 5 + 2x = -3 3/8 and subtract 5 from both sides (to get rid of the 5 on the left)

The equation turns into this: 2x = -8 3/8.

Now we can divide by 2 on both sides.

The equation becomes x = -4 3/16.

Hope this helps!

Answer:

31

Step-by-step explanation:

They're technically asking you to find the missing angle. 61+57 is 118. 180-118 is 62. Since they're asking  2x, you do 62 divided by 2, which is 31.

Answer:

100:60:80

Step-by-step explanation:

240÷12=20

20×5=100

20×3=60

20×4=80

Answer:

100: 60: 80

Step-by-step explanation:

5/(5+3+4) *240= 100

3/(5+3+4)* 240= 60

4/(5+3+4)* 240= 80

Hi there!

[tex]\large\boxed{c = 9, (x +3)^2}[/tex]

To find the value of c, we can say:

ax² + bx + c

(b/2)² = c

Therefore:

(6/2)² = 3² = 9

Rewrite the trinomial:

x² + 6x + 9

To write as a binomial, take the square root of c:

√9 = 3

Thus:

(x + 3)² = x² + 6x + 9

Step-by-step explanation:

Answer:

p = -2

Step-by-step explanation:

15 = -4p + 7

4p + 15 = 7

4p + 15 - 15 = 7 - 15

4p = -8

4p/4 = -8/4

p = -2

Answer: 36.2

Step-by-step explanation:

divide 30 by two (15)

use the pythagorean theorem (a^2+b^2=c^2)

15^2+33^2=x^2

225+1089=x^2

1314=x^2

Answer:

Step-by-step explanation:

18 - 7m > 0 ⇒ 7m < 18 ⇒ m < 18/7

Answer:

[tex] \displaystyle m_{1} = 2 \quad \text{and} \quad \displaystyle m _{2} = - 9[/tex]

Step-by-step explanation:

we are given a logarithm equation

[tex] \displaystyle \log_{4}( {m}^{2} ) = \log_{4}(18 - 7m) [/tex]

notice that, we have [tex]\log_4[/tex] both sides therefore we can get rid of it

[tex] \displaystyle {m}^{2} = 18 - 7m[/tex]

in order to solve it we should make it standard form we know that

[tex] \displaystyle a {x}^{2} + bx + c = 0[/tex]

so right hand side expression to left hand side and change its sign:

[tex] \displaystyle {m}^{2} + 7m- 18=0[/tex]

now we can solve it by using factoring method

to do so rewrite the middle term as sum or subtraction of two different terms

in that case -2m+9m is good to use

[tex] \displaystyle {m}^{2} - 2m + 9m - 18 = 0[/tex]

factor out m:

[tex] \displaystyle m({m}^{} - 2 )+ 9m - 18 = 0[/tex]

factor out 9:

[tex] \displaystyle m({m}^{} - 2 )+ 9(m - 2)= 0[/tex]

group:

[tex] \displaystyle (m - 2)(m + 9) = 0[/tex]

hence,

[tex] \displaystyle m_{1} = 2 \quad \text{and} \quad \displaystyle m _{2} = - 9[/tex]

remember that,

when we deal with logarithm equation we should always check the roots

let's check the root 1:

[tex] \displaystyle \log_{4}( {2}^{2} ) \stackrel{?}{=} \log_{4}(18 - 7.2) [/tex]

simplify square:

[tex] \displaystyle \log_{4}( 4) \stackrel{?}{=} \log_{4}(18 - 7.2) [/tex]

simplify multiplication:

[tex] \displaystyle \log_{4}( 4) \stackrel{?}{=} \log_{4}(18 - 14) [/tex]

simplify substraction:

[tex] \displaystyle \log_{4}( 4) \stackrel{?}{=} \log_{4}(4) [/tex]

simplify logarithm:

[tex] \displaystyle 1 \stackrel{ \checkmark}{=} 1[/tex]

let's check root 2:

[tex] \displaystyle \rm \log_{4}( { - 9}^{2} ) \stackrel{?}{=} \log_{4}(18 - 7.( - 9)) [/tex]

simplify square:

[tex] \displaystyle \rm \log_{4}( 81 ) \stackrel{?}{=} \log_{4}(18 + 63) [/tex]

simplify addition:

[tex] \displaystyle \rm \log_{4}( 81 ) \stackrel{ \checkmark}{=} \log_{4}(81) [/tex]

therefore,

[tex] \displaystyle m_{1} = 2 \quad \text{and} \quad \displaystyle m _{2} = - 9[/tex]

Option 3 is the correct answer

Answer:

a = 65

b = 73

c = 17

d = 138

Step-by-step explanation:

d + 42 = 180

d = 138

c + d + 90 + 115 = 360

c + 138 + 205 = 360

c + 343 = 360

c = 17

90 + b + c = 180

90 + b + 17 = 180

b + 107 = 180

b = 73

a + b + 42 = 180

a + 73 + 42 = 180

a + 115 = 180

a = 65

Answer:

a is 65

b is 73

c is 17

d is 138

Step-by-step explanation:

The formulas are in the previous questions.

Answer:

One solution, A) (2 , -1)

Step-by-step explanation:

The solution is where the two lines intersect. If the lines do not intersect, it is no solution. If the line intersects once (like in the picture), it has one solution. If it intersects more than once (x), then it will have x amount of solutions.

In this case, the intersection is at (2 , -1), therefore, A) (2 , -1) is your answer.
