-3w-5(4x-4w)-4x

multiply the bracket by -5

(-5)(4x)=-20x

(-5)(-4w)=20w

-3w-20x+20w-4x

-3w+20w-20x-4x ( combine like terms)

answer:

17w-24x or -24x+17w

A rectangle has a a width of 9 inches the area is 648 inches what is the length of the rectangle
yuradex [85]
The formula for a rectangle is length*width=area. Since we know the area and the width, we plug it in to the formula, we get length*9=648. 
l*9=648 is equivalent to l=648/9. Now we solve <span>l=648/9 and get l=72. SO the width is 72 inches. </span>

Which shows the image of quadrilateral ABCD after the transformation R0, 90°?
avanturin [10]

Answer:

A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)

Step-by-step explanation:

The coordinates of rectangle ABCD are A(-1,0), B(0,-1), C(-2,-3), (-3,-2).

The mapping for a rotation through 90° clockwise about the origin is

(x,y)\to ( - y,x)

Therefore:

A(-1,0)\to A'(0,-1)

B(0,-1)\to B'(1,0)

C(-2,-3)\to C'(3,-2)

D(-3,-2)\to D'(2,-3)

Therefore the image rectangle has coordinates:

A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)

The first choice is correct.

Find the surface area of the given prism​
Wewaii [24]

Answer:

Hello! answer: 432

Step-by-step explanation:

12 × 8 = 96

12 × 8 = 96

12 × 6 = 72

12 × 6 = 72

8 × 6 = 48

8 × 6 = 48

Then you add them all up so...

96 + 96 + 72 + 72 + 48 + 48 = 432 therefore the surface area is 432 hope that helps!
