Answer:

c = 7

Step-by-step explanation:

We know that a right triangle = 90 degrees, so we can set up the equation of (8c - 5) + (6c - 3) = 90. From there on, we can simplify to get 14c - 8 = 90, and then 14c = 98. Dividing 14 from both sides we get c = 7.

Answer:

x²+12x+36 =0

Step-by-step explanation:

Hii, so I'm assuming your equation is equal to 0-->

x²+_x+36 =0

this could go many ways..

x²+12x+36 =0

which factor to (x+6)(x+6)

x²+15x+36 =0

which factor to (x+12)(x+3)

x²+13x+36 =0

which factor to (x+9)(x+4)

If I had to choose a answer.. I would go with the 1st option x²+12x+36 =0

Hope this helps, if there was more to this question, leave a comment and I can come back and help you ;)

Can anyone please help me with this?

Answer:

m∠QPT = 110°

Step-by-step explanation:

1. We can use exterior angle theorem to find m∠QPT. Exterior Angle Theorem states that the exterior angle of a triangle is equal to the sum of the two remote angles in that same triangle.

  • This means that 6x + 20 = x + 40 + 4x - 5. Then, we can plug in the value of x into 6x + 20 and find the measure of ∠QPT.

2. (Solving)

Step 1: Combine like terms.

  • 6x + 20 = (x+4x)+(40-5)
  • 6x + 20 = 5x + 35

Step 2: Subtract 20 from both sides.

  • 6x + 20 - 20 = 5x + 35 - 20
  • 6x = 5x +15

Step 3: Subtract 5x from both sides.

  • 6x - 5x = 5x +15 - 5x
  • x = 15

Step 4: Check if solution is correct.

  • 6(15)+20=(15)+40+4(15)-5
  • 90 + 20 = 15 + 40 + 60 - 5
  • 110 = 55 + 60 - 5
  • 110 = 115 - 5
  • 110 = 110

3. Now, let's plug in 15 for 6x + 20:

  • 6(15)+20
  • 90+20
  • 110

Therefore, m∠QPT = 110°.
