Can someone help me? It's urgent and thank you!
mr_godi [17]

Answer:

35 or A

Step-by-step explanation:

This is a combinations problem because the order doesn't matter (it's a council, not like president and v.p.). C(7, 3) is 7!/(4!*3!) = 7*6*5/3*2 = 35. Hope this helps! :)

Use the Distributive Property to expand this expression.<br><br> z(–6.4 – 3.5x)
dedylja [7]

Answer:

z\left(-6.4\:-3.5x\right)=-6.4z-3.5zx

Hence, Option 'C' is true.

Step-by-step explanation:

Given the expression

z\left(-6.4\:-3.5x\right)

Apply distributive law:   a\left(b-c\right)=ab-ac

Here:  a=z,\:b=-6.4,\:c=3.5x

so the expression becomes

z\left(-6.4\:-3.5x\right)=z\left(-6.4\right)-z\cdot \:\:3.5x

                         =-6.4z-3.5zx                 ∵  +\left(-a\right)=-a

Therefore,

z\left(-6.4\:-3.5x\right)=-6.4z-3.5zx

Hence, option 'C' is true.
