Answer:
The roots of the equation for the given quadratic equation is
.
Step-by-step explanation:
Given quadratic equation as :
2 x² + 8 x + 5 = 0
The roots of the quadratic equation ax² + bx + c = 0 as can be find as :
x = 
x = 
or, x = 
Or, x = 
Or, x = 
∴ x = 
Hence The roots of the equation for the given quadratic equation is
. Answer

Step-by-step explanation:
Answer:11.5
Step-by-step explanation:
distance=6 2/5 + 2 3/4 + 2 1/3
d=(5x6+2)/5 + (4x2+3)/4 + (3x2+1)/3
d=32/5 + 11/4 + 7/3
d=(12x32+15x11+20x7) ➗ 60
d=(384+165+140) ➗ 60
d=689 ➗ 60
d=11.5
Answer:
C
Step-by-step explanation:
Both triangles have three angles of the same value.
Remember that the angles in all triangles add up to 180°.
Let's use that to find out the unknown angles.
For the first triangle:
180 - 82 - 43 = 55°
55° is also in the second triangle.
Let's check with the second triangle:
180 - 82 - 55 = 43°
43° is also in the first triangle.
Therefore, both triangles are similar as the angles in both triangles are the same - 82°, 43° and 55°.
Hence, C.
