D = b^2 - 4ac = 7^2 - 4*2*6 = 49 - 48 = 1 So there are 2 roots and
the roots are real and rational
b
Area of equilateral triangle is whose side is given a = √3a^2/4
area of triangle 1/2*base * height
base =a
but height = √ a^2 - a^2/4
= √4a^2/4 - a^2/4.
=√3*a/2
now the formula is area of euqilateral traingle is 1/2*a*√3a/2
√3*a^2/4
No, since it is absolute value. The answer would simply be 5, since 5 - 10 is in the absolute value bars.
Answer:
a) x = 12
b) right triangle
Step-by-step explanation:
a) 2x + 1 + 5x + 5 + 90 = 180
7x + 96 = 180
180 - 96 = 84
84 / 7 = 12
x = 12
b) you can tell that it is a right triangle because of the square in the corner that indicates it is a right triangle
