Answer:
the answae is D THEN C THE. 1
Answer:
x = - 4
Step-by-step explanation:
Given
r(x) = - 5x - 1 and r(x) = 19, then equating the right sides gives
- 5x - 1 = 19 ( add 1 to both sides )
- 5x = 20 ( divide both sides by - 5 )
x = - 4
5y + 3 > -7 y + 13
Subtract 3 from both sides
5y > -7y + 13 - 3
Add 7y to both sides
5y + 7y > 13 - 3
12y > 10
Divide by 12, which is positive so the sign doesn't flip
y > 10/12 = 5/6
Answer: y > 5/6
Before you begin, familiarize yourself and keep in mind the
order of operations- PEMDAS (parenthesis, exponents, multiplication, division,
addition, subtraction). You must do all math problems using this.
17. Add all the
numerators since they are like-terms. 12/3 – then simplify it – 4.
18. Do the inner most
parenthesis first, add the numerators – 3/5. To multiply a fraction and a whole
number, multiply the numerator and the whole number, and then simplify – 15/5,
3, then divide 15 by 3 – and your answer
is 5.
19. Parenthesis first – 10/6. Then multiply the numerator
and the whole number and simplify – 120/6 – 20.
20. Parenthesis – 4.2 – multiply by 8 – 33.6.
21. Parenthesis – 4 – multiply by 3.6 – 14.4.
22. PEMDAS, so division goes before subtraction – 8.4.
Try the rest for yourself; that’s the only way you’ll learn.

(x+5) represents each side of a square. Since all sides of a square are equal, we know that all sides are (x+5).
Base x height = (x+5)(x+5)
Which is x^2+10x+25!
