Answer: 24

Step-by-step explanation:

Since we are given the value for m and n, we can plug them in and solve the expression.

3(4)+6(3)-6          [multiply]

12+18-6                [add]

30-6                     [subtract]

24

Now, we know the value of the expression is 24.

Q1.

Angle BAD is adjacent to angle CAD

which means they are equal

so angle BAD = 26 degrees


Q2.

Angel BAC = the sum of angles BAD and CAD

because they are adjacent angles

To find the angles we solve the equations

9x-5 = 3x+7

9x-3x = 7+5

6x = 12

x = 12/6

x = 6

5g + 4(-5+3g) = 1 - g
Korvikt [17]
5g + 4(-5 + 3g) = 1 - g 
5g - 20 + 12g = 1 - g 
 17g - 20 = 1 - g 
   \frac{18g}{18} =   \frac{21}{18}
    there can be to answer 
      g = \frac{21}{18} or 
      you can simplify \frac{21/3}{18/3} =  \frac{7}{6} or 1 \frac{1}{6}

$ PS = \frac{4}{3} x

Solution:

Given PRQ is a triangle.

ST is a line parallel to RQ.

$PT = x, \ PQ = 3x,  \ SR=\frac{8}{3}x

TQ=PQ-PT

TQ=3x -x=2x

<u>Triangle proportionality theorem,</u>

<em>If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.</em>

$\frac{PS}{SR} =\frac{PT}{TQ}

$\frac{PS}{\frac{8}{3} x} =\frac{x}{2x}

Do cross multiplication, we get

$ PS \times 2x=x \times \frac{8}{3} x

Divide by 2x on both sides, we get

$ PS = \frac{4}{3} x
