4.9x10^11.
One can solve this question by converting 1,400,000 into scientific notation. The equation then becomes --> (1.4x10^6)(3.5x10^5). Then, one can multiply 1.4 by 3.5 and use exponent laws to get x10^11.
1.4x3.5 = 4.9
(10^6)(10^5)=10^11
Therefore, the answer will be 4.9x10^11.

|x+18|=1

zepelin [54]

The absolute value, or modulus, of a number is its distance from zero, or essentially its magnitude.

The absolute value produces a positive answer.

We have this definition for the absolute value, taking into account its different values for different signs:

$|x|= \left \{ {{x, \ \ \ x \ \geq \ 0} \atop {-x, \ \ \ x \ \ \textless \ \ 0}} \right.$

Thus, for $|x+18|=1$ , we split the absolute value as such:

$x+18=1$ and $x+18=-1$

We solve each case.

$x=-17$ and $x=-19$

We check these solutions.

$|-17+18|=1\\|1|=1\\1=1$
and
$|-19+18|=1\\|-1|=1\\1=1$

The angles of an equilateral triangle are congruent. If x represents the measure of one angle of an equilateral triangle, which

dezoksy [38]

4) x + x + x = 180°

An equilateral triangle has three sides of equal length. Its interior angles are also equal. Since interior angles of a triangle should sum up to 180°, then each angle is 60°, making each angle congruent with one another.

So if x is equal to one angle and triangles have three angles then,

x + x + x = 180°

or 3x = 180°
