x^2 = 100...by taking the square root of both sides, this eliminates the ^2
x = (+-) sqrt 100
x = (+-) 10
so the values of x are -10 and 10
Answer:
D
Step-by-step explanation:
a perfect square trinomial is
factorized is
so as you can see option A and B can't be, because they have -49y^2 and it has to be plus
so the other options are C and D
in the trinomial a=4 and b=\pm 7
the roots of a^2 and b^2
so it's option d with b=-7
The numerical value of the first check will be $2,357.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
A business owner issues a paycheck in the amount of two thousand, three hundred fifty-seven dollars and forty-nine cents.
Then the numerical amount of this check will be
The numerical value of the check will be
Two thousand, three hundred fifty-seven dollars and forty-nine cents = $2,357.49
The numerical value of the first check will be $2,357.49.

Triangles ABC and ADE are similar triangles. That means the sides are all scaled by the same factor.
To go from side BC to side DE, you multiply by 1.25. That means 1.25 is your scale factor. Now apply that factor to the bottom side to get your answer.
Side AB is 6. That means side AD is 6 x 1.25 = 7.5. That means x = 7.5 - 6 = 1.5
