Simplify this 13.) 13y² + 9y + 4y² - 31y

erastova [34]

Answer: $17y^2-22y$

Step-by-step explanation:

$13y^2+9y+4y^2-31y$

$\mathrm{Group\:like\:terms}$

$=13y^2+4y^2+9y-31y$

$\mathrm{Add\:similar\:elements:}\:13y^2+4y^2=17y^2$

$=17y^2+9y-31y$

$\mathrm{Add\:similar\:elements:}\:9y-31y=-22y$

$=17y^2-22y$

Can I make a right angle by drawing an acute angle and and an obtuse angle that share a common ray?

Trava [24]

Yes you could because the obtuse angle is greater than 90 degrees so if the acute angle is inside the obtuse you could get an right angle or an 90 degree angle

5x/x^2-9 + 7/x+3<br> Simplify

rjkz [21]

5x ÷ x² - 9 + 7 ÷ x + 3

Write the division as a fraction:

$\frac{5x}{x^{2} }\\$ - 9 + $\frac{7}{x}$ + 3

Simplify the expression:

$\frac{5}{x}$ - 9 + $\frac{7}{x}$ + 3

Calculate the sum:

$\frac{5}{x}$ - 6 + $\frac{7}{x}$

Write all numerators above the common denominator:

$\frac{5 - 6x + 7}{x}$

Add the numbers and you get the final answer:

$\frac{12-6x}{x}$
