Answer:
D.) 8x^2+11x-9
Step-by-step explanation:
5x^2 -(-3x^2) =8x^2
7x -(-4x) =11x
-4 -5 =-9
Hope it helps
What exactly are we solving?? the rest of the angles or the perimeter?

Question 2.2. Which ordered pairs make the inequality true?</span><span>2x + y > –4</span>The solutions are (-1, 2) and (1, -5), look at the graph in the attachment.
Question 3.3. What is the slope of the line represented by the equation?There is no equation
Question 4.4. What is the slope of the line represented by the equation 6x - 3y = 4?Convert to slope-intercept form:
6x - 3y = 4
Subtract 6x to both sides:
-3y = -6x + 4
Divide -3 to both sides:
y = -6/-3x + 4/-3
Simplify:
y = 2x - 4/3
Now it's in slope intercept form, y = mx + b, where 'm' is the slope. So the slope here is 2.
Question 5.5. What is the simplified form of the expression?15y - 3(4y + 10)
Distribute -3 into the parenthesis:
15y - 12y - 30
Combine like terms:
3y - 30
Answer: Rounded to the nearest tenth is 5
4.96894409 is the exact answer
There are 2 zeros in the product.
6*5=30
30*10=300
2 zeros
