Answer:
Step-by-step explanation:
x2 - 4x - 12 = 0
x2 - 6x + 2x - 12= 0
x(x - 6) + 2(x - 6) = 0
x + 2 = 0
x = - 2
x - 6 = 0
x = 6
Answer:
1.37
Step-by-step explanation:
that is half of 2 and 3/4
10. As 8x = 2x + 60. So x =10
Answer:
Area = 127.5cm²
Step-by-step explanation:
Given that,
Length of first side = 8 cm
Length of second side = 15 cm
Length of third side = 17cm
To find,
Area of triangle
to find which of the sides is hypotenuse use Pythagorus theorem
hypotenuse² = height² + base²
17² = 8² + 15²
289 = 289
hence 17 is the hypotenuse and other two are height and base
<h2>Area of triangle = 1/2 height * base</h2>
Area of triangle = 1/2 15 * 17
Area of triangle = 1/2 (255)
Area of triangle = 127.5
