Here it is, step by step:
x^2 - 10x = -34
x^2 - 10x + 34 = 0
We cannot easily factor anything, so we resort to the quadratic equation. The work is attached as an image.
Answer:
3( root 3 /2)^2 + 3/4 (root 3 )^2 - 2(2/ root 3) ^2 - 3/4 (1/root3)^2
= 3 ×3 /4 + 3 × 3 /4 - 2 ×4 /3 - 3/4 × 1/3
= 9/4 + 9/4 -8/ 3 - 1/4
= 9/4 + 9/4 - 1/4 - 8/3
= 17/4 - 8/3
=( 17 × 3 - 8 × 4 )/12
= (54 -32)/12
= 19 /12
Answer:
x = 21
Step-by-step explanation:
Vertical angles are congruent, this
3x - 30 = 2x - 9 ( subtract 2x from both sides )
x - 30 = - 9 ( add 30 to both sides )
x = 21
