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.

The length of a rectangle is eight more

tatyana61 [14]

Answer:

Width of the rectangle = 13.16 ft

Length of the rectangle = 34.33 ft

Step-by-step explanation:

Let the width of the rectangle = k ft

So, the length of the rectangle = (2k + 8) ft

Perimeter of the rectangle = 95 ft

PERIMETER OF THE RECTANGLE = 2(LENGTH +WIDTH)

⇒ 2( k+ (2k+ 8)) = 95

or, 2( 3k + 8) = 95 ⇒ 6k + 16 = 95

or, 6k = 95 - 16 = 79

⇒ k = 79/ 6 = 13.16

So, the Width of the rectangle = k = 13.16 ft

Now, Length of the rectangle = 2(13.16)+ 8 = 34.33 ft
