-7a+6a^2-10
I am assuming you are solving to get a zero, in which case a=2

The factors are (a - 2) and (6a + 5) . If the expression is equal to zero, then 'a' can be 2, and 'a' can be -5/6 .

The volume of gas in a container at a constant temperature varies inversely as the pressure. If the volume is 32 cubic centimete

aleksklad [387]

Step-by-step explanation:

Given that,

The volume of gas in a container at a constant temperature varies inversely as the pressure.

$V_1=32\ cm^3\\\\P_1=8\ \text{pounds}\\\\V_2=60\ cm^3$

We need to find pressure $P_2$ .

According to question,

$\dfrac{V_1}{V_2}=\dfrac{P_2}{P_1}$

Putting all the values

$P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{8\times 32}{60}\\\\P_2=4.26\ \text{pounds}$

So, the pressure is 4.26 pounds.

3/4^2 + 1^2 = x2<br><br> solve for x with work shown! pls help!

photoshop1234 [79]

Answer:

X=19/32

Step-by-step explanation:

3/4^2+1^2=2*x

3/4^2+1=2x

3+(4^2)/4^2=2x

3+16/4^2=2x

19/4^2=2x

19/(2^2)^2=2x

19=16(2x)

19=16*2x

32x=19

32x/32=19/32

x=19/32

This took alot of time goodluck!
