It is important to remember that in simplifying expressions, you can only add or subtract like terms. Also, you have to follow PEMDAS. For the expression,
<span>5 + 7 + 15xy^2 + 9y^3 + 10x –13xy^2 – 3x – 8y^3
We can combine all the constants, xy^2 terms, y^3 terms and x terms which will yield,
12 + 2xy^2 + y^3 + 7x
Therefore the correct answer is option B.</span>
Answer:
for the first one do 15 divided by 10 and the second one 18 divided by 8.
Step-by-step explanation:
Step-by-step explanation:
A triangle's angles add up to be 180 degrees, so you can create an equation to be 180= 130+5x. (the 5x is 2x + 3x)
subtract 130 from both sides and get 50=5x, divide both sides by 5, x is equal to 10.
I'm not sure which angle is angle a, but if you substitute x with 10, you can find the measure of the angle, so if it's 2x, 2(10)=20 and if 3x, 3(10)=30
Step-by-step explanation:
y = -2x² + 9x - 11 (2 complex solutions)
y = 3x² - 6x + 3 (1 distinct real solution)
y = -x² - 4x + 7 (2 real solutions)
