Negative 10.9p plus 3.9 equals negative 9.18.... what does p equal

Julli [10]

Answer:

-1.2

Step-by-step explanation:

$10.9p+3.9=-9.18$

Subtract 3.9 from -9.18 to isolate the variable.

$10.9p=-13.08$

Divide -13.08 by 10.9

$-13.08/10.9=-1.2$

Which equals

$p=-1.2$

Find the square: (5x - 4y)2 <br><br> (and please put the process of solving the equation)

satela [25.4K]

$(5x-4y)^2$
$(5x-4y)(5x-4y)$

Multiply each term in one bracket in turn by the terms in the other bracket

$(5x)(5x) = 25x^2$
$(5x)(-4y)=-20xy$
$(-4y)(5x)=-20xy$
$(-4y)(-4y)=16y^2$

Put them together we have
$25x^2-20xy-20xy-16y^2$
$25x^2-40xy-16y^2$
