Answer: The value of z is -0.75.

Step-by-step explanation:

The given equation is 3.5z-2.7z=-6

In term to solve it to find z ,  we first simplify the left side.

By using distributive property :ba+ca=(b+c)a , we get

(3.5-2.7)z=-6\\\\\Rightarrow 0.8z=-6

Now , Divide both sides by 0.8 , we will get

z=\dfrac{-6}{0.8}=\dfrac{-60}{8}\\\\\Rightarrow\ z=-7.5

Hence, the value of z is -0.75.

Which factor do 64x^2 + 48x + 9 and 64x^2 - 9 have in common?
Ber [7]
Start with the second expression.  That factors easily into (8x-3)(8x+3).
Since 64x^2 + 48x + 9 has no negative signs, I'd bet that the common factor is (8x+3).  Divide  <span>64x^2 + 48x + 9  by that to verify.

587×6543÷285{32+65}= ? HELP
Ludmilka [50]

Answer:

1307199.57

Step-by-step explanation:

Follow BEDMAS (brackets first, then exponents, then multiplication and division, then addition and subtraction)

587x6543÷285(32+65)

32+65=97

587 x 6543 ÷ 285 x 97

= 3840741 ÷ 285 x 97

= 13476.2842 x 97

= 1307199.57

If (a+b)=4 and ab=3 find the value of a3 +b3<br>​
elena-14-01-66 [18.8K]
I think this might be the answer since (a+b) equals 4, and ab= 3. I'm not sure.
a3 + b3
= (4)3+4(3)
= 12+12
= 24
