This is because the sum of 2 sides of a triangle has to be greater than the side that was not used
Answer:
40.5 cm
Step-by-step explanation:
So think about it what is the Formula for a Trapezoid? Well it's h(b1+b2)/2! So we use this formula and place the numbers in there! When you're done you should have this: 6(9+4.5)/2. Now we will do <u>PEMDAS</u> (parenthesis, exponents, multiplication, division, addition, subtraction). from left to right. So we first do 9+4.5. That equals 13.5. Then we times that by 6, which is 81. Then we finally divide it by 2. Then there's your answer! :D
Subtract sqrt(3) to both sides so that the equation becomes -3x^2 + 7x + 2 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [-b ± √(b^2 -4ac) ] / (2a)
x = [ -7 ± √((7)^2 - 4(-3)(2)) ] / ( 2(-3) )
x = [-7 ± √(49 - (-24) ) ] / ( -6 )
x = [-7 ± √(73) ] / ( -6)
x = [-7 ± sqrt(73) ] / ( -6 )
x = 7/6 ± -sqrt(73)/6
The answers are 7/6 + sqrt(73)/6 and 7/6 - sqrt(73)/6.
