What is (3x+5)(x^2+6x+11)

serg [7]

Answer:

$\large\boxed{3x^3+23x^2+63x+55}$

Step-by-step explanation:

$\text{Use FOIL:}\\\\(a+b)(c+d)=ac+ad+bc+bd$

$(3x+5)(x^2+6x+11)\\\\=(3x)(x^2)+(3x)(6x)+(3x)(11)+(5)(x^2)+(5)(6x)+(5)(11)\\\\=3x^3+18x^2+33x+5x^2+30x+55\qquad\text{combine like terms}\\\\=3x^3+(18x^2+5x^3)+(33x+30x)+55\\\\=3x^3+23x^2+63x+55$

Find the product. (-4-3-2)^2

kumpel [21]

Answer:

Hi there!

Your answer is:

Step-by-step explanation:

First, simplify within parentheses.

-4-3-2 = -7-2 = -9

(-9)^2

The negative is within the parentheses, so it goes away when squared

(-9)^2 = -9× -9= 81

Hope this helps

What is 9/16 + 1/2 simplified

trasher [3.6K]

$\frac{9}{16}$ + $\frac{1}{2}$

First, find the least common denominator (LCD) of the two fractions.
Multiples of 16: 16
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16
The LCD is 16.
Second, make the denominators the same as the LCD. / Your problem should look like: $\frac{9}{16}$ + $\frac{1x8}{2x8}$
Third, simplify. The denominators are now the same. / Your problem should look like: $\frac{9}{16}$ + $\frac{8}{16}$
Fourth, join the denominators. / Your problem should look like: $\frac{9+8}{16}$
Fifth, simplify. / Your problem should look like: $\frac{17}{16}$
Sixth, convert to mixed fraction. / Your problem should look like: $1 \frac{1}{16}$

Answer: $1\frac{1}{16}$
