What is the value of b11?

Novay_Z [31]

Since Matrix A is added with Matrix B
then each component must be added to its corresponding component
a11+b11=0
a11=-b11
if
a11*b11=-16
then a11=+4 and b11=-4 or a11=-4 and b11=4
a11 is postive so our answer should be
a11=4 and b11=-4

Twice "a" increased by the cube of "a" equals b.

MrRa [10]

Answer:

$2a+a^3=b$

Step-by-step explanation:

Let's do it part by part:

<u>Twice "a":</u>

This means 2 times a, or 2*a

<u>Cube of "a":</u>

This means a cubed, so a to the power 3, or $a^3$

Also note "is" means "equal" and "of" means "multiplication.

Twice a increased by cube of a means both parts are summed so we have:

$2a+a^3=b$ \

This is the formula/equation
