7W + 3 = -4W - 85 a. -11b. 11c. 8d. -8

1 answer:

6 0

-8
Step 1) Subtract 3 from both sides of the equation
Step 2) Add 4W to both sides of the equation
Step 3) Divide both sides of the equation by the same factor

For f(x) = 4x +1 and g(x) = x2 - 5, find (f-8)(x).

Mariana [72]

Answer:

(f-g)(x) = -x² +4x +6

Step-by-step explanation:

We assume you want to find (f -g)(x).

$(f-g)(x)=f(x)-g(x)=(4x+1)-(x^2-5)\\\\\boxed{(f-g)(x)=-x^2+4x+6}$

Find the surface area of the composite figure

Gnoma [55]

Answer:

$=280$ $in^2$

Step-by-step explanation:

----------------------------------------

Let's find the surface area of the pink rectangular prism first.

$2*10=20+20=40$

$4*10=40+40=80$

$4*2=8+8=16$

$40+80+16=136$

The surface area for the pink rectangular prism is $136$ $in^2$ .

-------------------->>>>>

Now, let's find the surface area of the green rectangular prism.

$4*7=28+28=56$

$4*4=16+16=32$

$56+56+32=144$

The surface area for the green rectangular prism is 144 $in^2$ .

-------------------->>>>>

Now let's add the surface area of both rectangular prisms to find the surface area of the composite figure.

$136+144=$

$=280$ $in^2$

----------------------------------------

Hope this is helpful.

Divide 6.391 Ã· 0.57. Round the quotient to the nearest hundredth.

Paul [167]

The answer is 11.21, dividing 6.391 by 0.57 will give you 11.2122807018.
Rounding to 11.21 because the thousandths place is less then 5 so the hundredths place stays the same.
