Answer:

X^2-x- 8/x+4

Step-by-step explanation:

X+4 becomes a negative 4

Then multiply -4 by the first number which is 1 so -4×1 is -4. Then subtract -4 by the second number 3. This gives you -1 so multiply that by 4 which is -4. Then subtract 4 from the third number -4. So that'll give you -8. Then add an x-value to every number except the very last number as that number will be you remainder.

Answer:

25

Step-by-step explanation:

Answer:

x = 65

Step-by-step explanation:

Corresponding angles always equal each other;

2x + 5 = 135

Subtract 5 from both sides;

2x = 130

Divide both sides by 2;

x = 65

The value of the variable x will be 2. Then the radius of the circle will be 5.

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

The radius of the circle is x + 3. And the area of the circle is 25π. Then the equation will be

25π = π(x + 3)²

(x + 3)² = 25

x + 3 = 5

x = 5 - 3

x = 2

Then the radius will be

r = x + 3 = 2 + 3 = 5

The value of the variable x will be 2. Then the radius of the circle will be 5.

[1]   x + 5y - 4z = -10

[2]   2x - y + 5z = -9

[3]   2x - 10y - 5z = 0

Eliminate x by adding -2[1] to [2], and adding -1[2] to [3]:

-2(x + 5y - 4z) + (2x - y + 5z) = -2(-10) + (-9)

-2x - 10y + 8z + 2x - y + 5z = 20 - 9

[4] -11y + 13z = 11

-(2x - y + 5z) + (2x - 10y - 5z) = -(-9) + 0

-2x + y - 5z + 2x - 10y - 5z = 9

[5]  -9y - 10z = 9

Eliminate y by adding -9[4] to 11[5]:

-9(-11y + 13z) + 11(-9y - 10z) = -9(11) + 11(9)

99y - 117z - 99y - 110z = -99 + 99

-227z = 0

z = 0

Plug this solution into either [4] or [5] and solve for y :

[5] -9y - 10(0) = 9

-9y = 9

y = -1

Plug them both into either of [1], [2], or [3] and solve for x :

[1] x + 5(-1) - 4(0) = -10

x - 5 = -10

x = -5

(2)

[1] 2x - y + z = -4

[2] z = 5

[3] -2x + 3y - z = -10

Substitute [2] into [1] and [3]:

2x - y + 5 = -4

[4] 2x - y = -9

-2x + 3y - 5 = -10

[5] -2x + 3y = -5

Solve [4] for y :

2x - y = -9

2x + 9 = y

Substitute this into [5] and solve for x :

-2x + 3(2x + 9) = -5

-2x + 6x + 27 = -5

4x = -32

x = -8

Plug this into either [4] or [5] to solve for y :

[4] 2(-8) - y = -9

-16 - y = -9

y = -5

Answer:

b=a √3

Step-by-step explanation:

Answer: x = 16   and the measure of angle is 59°.

Step-by-step explanation:

Complementary angles add up to 90 degrees. Meaning that, if you  add the two angles together and add them to equal 90 you can solve for x.

(x + 15) + (3x + 11) = 90       First combine like terms.

4x + 26 = 90   Subtract 26 from both sides.

    -26     -26

4x = 64

x = 16    

If x is equal to 16, then we can find the measure of angle N by inputting the value of x into the expression for the measure of angle N.

m∠N = 3(16) + 11  

m∠N = 48 + 11

m∠N = 59

Answer:

x=35, y=18

Step-by-step explanation:

the triangles are similar so they are in proportion

x/14=45/y= 40/16

[tex]\frac{x}{14} =\frac{40}{16}[/tex]  find x

[tex]x= \frac{14*40}{16} = 35[/tex]

[tex]\frac{45}{y} =\frac{40}{16}[/tex]  find y

[tex]y= \frac{45*16}{40} =18[/tex]
