Answer:

32

Step-by-step explanation:

Same factors meaning it is of the form

(x + a)(x + a) = (x + a)^2 = x^2 + 2ax + a^2

Take sqrt(256) = 16

a = 16, c = 2a = 32

Answer:

32

Step-by-step explanation:

Answer:

Simplifying

(7y + 27) + (15x + -5) = 125

Reorder the terms:

(27 + 7y) + (15x + -5) = 125

Remove parenthesis around (27 + 7y)

27 + 7y + (15x + -5) = 125

Reorder the terms:

27 + 7y + (-5 + 15x) = 125

Remove parenthesis around (-5 + 15x)

27 + 7y + -5 + 15x = 125

Reorder the terms:

27 + -5 + 15x + 7y = 125

Combine like terms: 27 + -5 = 22

22 + 15x + 7y = 125

Solving

22 + 15x + 7y = 125

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-22' to each side of the equation.

22 + 15x + -22 + 7y = 125 + -22

Reorder the terms:

22 + -22 + 15x + 7y = 125 + -22

Combine like terms: 22 + -22 = 0

0 + 15x + 7y = 125 + -22

15x + 7y = 125 + -22

Combine like terms: 125 + -22 = 103

15x + 7y = 103

Add '-7y' to each side of the equation.

15x + 7y + -7y = 103 + -7y

Combine like terms: 7y + -7y = 0

15x + 0 = 103 + -7y

15x = 103 + -7y

Divide each side by '15'.

x = 6.866666667 + -0.4666666667y

Simplifying

x = 6.866666667 + -0.4666666667y

Answer :

How do You find the right line of reflection? 

Step-by-step explanation:

The concept is the line y = x. (y, x). The point is on the line y = -x (-y, -x). Notice that each point of a reflected image is the same distance from the reflection line as the original figure's corresponding point. Between the original figure and its image, the line of reflection will be directly in the centre.

Question 8

Let the equation of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

y = mx + b

Here, m = slope and y-intercept = b

Since, m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

For two points (1, 4) and (5, 8),

m = [tex]\frac{8-4}{5-1}[/tex]

m = 1

Equation will be,

y = (1)x + b

y = x + b

Since, this line passes through (1, 4),

4 = 1 + b

b = 3

Therefore, equation of the line will be,

y = x + 3

Question 9

Let the equation is y = mx + b

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

For two points (2, 10) and (6, 4)

m = [tex]\frac{10-4}{2-6}[/tex]

m = [tex]-\frac{3}{2}[/tex]

By substituting the value of 'm' in the equation,

y = [tex]-\frac{3}{2}x+b[/tex]

Since, this line passes through (2, 10)

10 = [tex]-\frac{3}{2}(2)+b[/tex]

b = 10 + 2

b = 12

Therefore, equation of the line will be,

[tex]y=-\frac{3}{2}x+12[/tex]

Answer: a

Answer:

Dont think eh multiplied both sides by 4. That would be the first step.

Step-by-step explanation:

1/4(x+12)=2

multiply both sides by 4

x+12=8

move the 8 to the right side of the equation and change its sign

x=8-12

calculate

x= -4

Answer:

He didn't multiply 1/4 between both terms in the brackets.

Step-by-step explanation:

1/4(x+12)=2

1/4x+3=2

1/4x= -1

x= -4

Answer: 56.72 m, 72.6 m

Step-by-step explanation:

Given

The initial angle of elevation is [tex]38^{\circ}[/tex]

after walking 25 m, the angle of elevation is [tex]50^{\circ}[/tex]

In [tex]\triangle ABD[/tex]

[tex]\Rightarrow \tan 38^{\circ}=\frac{h}{x+25}[/tex]

[tex]\Rightarrow h=\tan 38^{\circ}(x+25)\quad \ldots(i)[/tex]

In [tex]\triangle ABC[/tex]

[tex]\Rightarrow \tan 50^{\circ}=\frac{h}{x}\\\\\Rightarrow h=x\tan 50^{\circ}\quad \ldots(ii)[/tex]

From (i) and (ii)

[tex]\Rightarrow x\tan 50^{\circ}=(x+25)\tan 38^{\circ}\\\Rightarrow 1.191x-0.781x=25\times 0.781\\\Rightarrow 0.4104x=19.532\\\Rightarrow x=47.59\approx 47.6\ m[/tex]

[tex]\Rightarrow h=47.6\times \tan 50^{\circ}=56.72\ m[/tex]

The distance of tree bottom and Chidi's  is

The equation of the dilated line is y = (3/5)x + (33/5), and it passes through the point (0,7).

To dilate the line y = 3x + 5 by a factor of 1/5 with (0,7) as the center of dilation, we can follow these steps:

Shift the line so that the center of dilation is at the origin. To do this, we subtract 7 from the y-intercept of the original line, giving us y = 3x - 2.

Apply the dilation factor to the line. To do this, we multiply the coordinates of each point on the line by 1/5. This gives us the new equation:

y = (3/5)x - (2/5)

Shift the line back to its original position. To do this, we add 7 to the y-intercept of the dilated line, giving us the final equation:

y = (3/5)x + (33/5)

Therefore, the equation of the dilated line is y = (3/5)x + (33/5), and it passes through the point (0,7).

Answer/Step-by-step explanation:

✔️Reference angle = 50°

Opposite side length = y

Hypotenuse = 8 cm

Adjacent = x

Thus, applying CAH we can find x as shown below:

Cos 50 = adj/hyp

Cos 50 = x/8

8 × cos 50 = x

x = 5.1 (to 1 decimal point)

Thus, applying SOH, we can find y as shown below:

Sin 50 = opp/hyp

Sin 50 = y/8

8 × Sin 50 = y

y = 6.1 (to 1 decimal point)

Answer: 165 different combinations.

Step-by-step explanation:

Here we first need to identify the "selections", and then the number of options for each selection.

Here we have two selections, shorts, and sleeveless blouses.

For shorts, we have 15 options.

For sleeveless blouses, we have 11 options.

The total number of combinations will be equal to the product between the numbers of options for each selection, then the total number of combinations is:

C = 11*15 = 165
