Take your problem and do 3x=x+40 and subtract the x from 3x and it should equal 2x then take 2x=40 divide 2x from 40 and your answer is 20

the 2 angles are congruent so...

x+40=3x    set the 2 equations equal to each other

40=2x      subtract x from both sides

20=x     divide by 2

x=20 is the final answer

Have a blessed day!

Hey!

---------------------------------------------------------------------

We know that (a = -3), (b = 2), (c = 5), and (d = -4)

---------------------------------------------------------------------

Question 6:

= 5ac - 2b

= 5(-3)(5) - 2(2)

= 5(-15) - 4

= -75 - 4

<u>= -79</u>

---------------------------------------------------------------------

Question 7:

= ab/d

= (-3)(2)/-4

= -6/-4

<u>= 1 1/2</u>

---------------------------------------------------------------------

Hope this helped, good luck!

The height of a trapezoid can be expressed as x – 4, while the bases can be expressed as x + 4 and x + 9. if the area of the tra
AlexFokin [52]

Answer: 19 cm

<u>Step-by-step explanation:</u>

A_{trapezoid}=\frac{b_{1}+b_{2}}{2}*h

                99 = \frac{(x+4 + x+9}{2}*(x - 4)

                99 = \frac{(2x + 13}{2}*(x - 4)

              198 = (2x + 13)(x - 4)

              198 = 2x² + 5x - 52

                 0 = 2x² + 5x - 250

                 0 = 2x²- 20x + 25x - 250

                 0 = 2x(x - 10) + 25( x - 10)

                 0 = (2x + 25)(x - 10)

0 = 2x + 25     or        0 = x - 10

  -\frac{25}{2} = x      or          x = 10

Since length cannot be negative, -\frac{25}{2} can be disregarded

Larger base: x + 9  = 10 + 9   = 19
