X=4
I'm gonna show you the step by step process
0.5*4=2
2-6=-4
and that is why x=4
Answer:
x = - 5 , x =
Step-by-step explanation:
the values of x that make f(x) zero are the zeros
to find the zeros let f(x) = 0 , that is
3x² + 13x - 10 = 0
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 10 = - 30 and sum = + 13
the factors are + 15 and - 2
use these factors to split the x- term
3x² + 15x - 2x - 10 = 0 ( factor the first/second and third/fourth terms )
3x(x + 5) - 2(x + 5) = 0 ← factor out (x + 5) from each term
(x + 5)(3x - 2) = 0
equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
3x - 2 = 0 ⇒ 3x = 2 ⇒ x =
I believe its the first four after the decimal
Answer:
<h2>1</h2>
Step-by-step explanation:
Having a certain triangle there are some cases of congruency:
SSS (side side side) All three corresponding sides are equal in length.
SAS (side angle side) A pair of corresponding sides and the included angle are equal.
ASA (angle side angle)
AAS (angle angle side)
As we can observe there must be always 3 components of congruency. Triangle ABC can be congruent to triangle ADC by SSS if we have 3 sides that are equal. We already have two components: AB=AD and AC=AC (AC is a common side) so we need the third component BC=CD. The answer to your question is option B.
