Solve for c: a(c−b)=d
Sindrei [870]

Answer:

a(c-b) = d

Use the distributive property, which states: x(y-z) = xy - xz

a(c-b) = ac - ab

ac - ab = d

Add ab on both sides

ac = d + ab

Divide both sides by a to isolate c

Step-by-step explanation:

Use the net:

Rectangle 1: (21 in + 3 in + 21 in + 3 in) by 15 in.

Rectangle 2: 21 in by 3 in

Rectangle 3: 21 in by 3 in

total area = sum of areas of 3 rectangles above.

total area = (48 in * 15 in) + 2(21 in * 3 in)

total area = 720 in^2 + 126 in^2

total area = 801 in^2

lara31 [8.8K]

Answer:

See below-

Step-by-step explanation:

It depends on if you are transforming O to P or P to O

O to P would be rotate counterclockwise translate down 4

using the point (-3,2) from P and it's corresponding point from O (6,3)

rotate 90 counterclockwise (x,y)--> (-y,x) From point O - (6,3)--> (-3,6)

so after the rotation that point would be at (-3,6) to get the point to (-3, 2) move it down 4. so it is translated down 4

if you are transforming O to P is would be the opposite

rotate 90 clockwise and translate up 4
