Find the value of x <br> (8x-1) (4x+7)
Helen [10]

Answer:

The value of x = 7

Step-by-step explanation:

Given the right triangle

  • Right angle = 90°
  • α = (4x+7)°
  • β =  (8x-1)°

  • We know that the sum of angles of a triangle is 180°.

so

Right angle + α + β =  180°

90° + 4x+7 + 8x-1 = 180

Group like terms

4x+8x+90+7-1=180

Add similar elements: :4x+8x=12x

12x+90+7-1=180

12x+96=180

12x=84

Divide both sides by 12

\frac{12x}{12}=\frac{84}{12}

x = 7

Therefore, the value of x = 7

Solve 3x^2 + x + 10 = 0 round solutions to the nearest hundredth
lara31 [8.8K]

Answer:

C. X= -2.01 and x= 1.67

Step-by-step explanation:

3x {}^{2}  + x + 10 = 0 \\ 3x {}^{2}  + 6x - 5x + 10 = 0 \\ 3x(x + 2) - 5(x + 2) \\ (x + 2)(3x - 5 )\\  x  + 2 = 0 \:  \: or \:  \: 3x - 5 = 0 \\ x =  - 2 \:  \: or \:  \: x =  \frac{5}{3}
