Answer:
<em>7</em>
Step-by-step explanation:
Sum of angles on a straight line is 180°
12x - 8 + 104 = 180°
12x + 96° = 180°
12x = 180° - 96°
<u>12x</u> = <u>8</u><u>4</u>
12 12
x = <em><u>7</u></em>
Answer:
yes
Step-by-step explanation:
divide each by 7 =
21/7 = 3
28/7 =4
35/7 = 5
3,4,5 are always a perfect triple, and multiples of 345 are perfect triples as well. Therefore, they are sides of a right triangle.
Answer:
a
Step-by-step explanation:
Discriminant D is given by:
D=b²-4ac
Implication of discriminant is as follows:
D<0 two zeros that are complex conjugate
D=0 one real zero of multiplicity 2
D>0 two distinct real zers
D= (+ve perfet square) two distinct rational zeros
From:
12x^2+10x+5=0
plugging in the equation we get:
10²-4×12×5
=100-240
=-140
thus
D<0
