Answer:
Step-by-step explanation:
5(x + 27) >= 6(x + 26)
5x + 135 >= 6x + 156
-x >= 21
x <= -21
Answer: Choice B.
Answer:

Step-by-step explanation:
<u>Step 1: Define</u>
-25x + 14 > 20
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 14 on both sides: -25x > 6
- Divide -25 on both sides: x < -6/25
Here we see that any number <em>x</em> less than -6/25 would work as a solution to the inequality.
Answer:
Step-by-step explanation:
we know that
In a 45-45-90 right triangle, the length of the two legs are equal
so
Applying the Pythagorean Theorem
where
c is the hypotenuse
a and b are the legs
we have
substitute
simplify
7x^2 -25y^2 -4x
Is the difference of the polynomials
