200 books x 30 boxes = 6000 books
6000 books x 20 shipping crates = 120,000 books
Just keep multiplying
Answer:
x=−1 or x=−6
Step-by-step explanation:
Multiply all terms by x and cancel:
xx+6=−7x
x2+6=−7x(Simplify both sides of the equation)
x2+6−−7x=−7x−−7x(Subtract -7x from both sides)
x2+7x+6=0
(x+1)(x+6)=0(Factor left side of equation)
x+1=0 or x+6=0(Set factors equal to 0)
x=−1 or x=−6
Check answers. (Plug them in to make sure they work.)
x=−1(Works in original equation)
x=−6(Works in original equation)

Answer:
1. x/2=1.75/3.5 x=1
2. 4/2=y/3.5 y=3.5
3. P (Figure Left)=3+5+2+1+4+8+3+2=28 cm
A (Figure Left)=8x2-2x1-3x2=8 cm2
4. P (Figure Left) / P (Figure Right) = 1/1.75 = 28/ P (Figure Right)
P (Figure Right)= 49 cm
A (Figure Left) / A (Figure Right) = 1/1.752 = 8/ A (Figure Right)
A(Figure Right)= 24.5 cm2
Step-by-step explanation:
1. x/2=1.75/3.5 x=1
2. 4/2=y/3.5 y=3.5
3. P (Figure Left)=3+5+2+1+4+8+3+2=28 cm
A (Figure Left)=8x2-2x1-3x2=8 cm2
4. P (Figure Left) / P (Figure Right) = 1/1.75 = 28/ P (Figure Right)
P (Figure Right)= 49 cm
A (Figure Left) / A (Figure Right) = 1/1.752 = 8/ A (Figure Right)
A(Figure Right)= 24.5 cm2

Answer:
-7
Step-by-step explanation:
Since we have two points, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 20-6)/(-6- -4)
= ( 20-6)/ ( -6+4)
= 14/-2
= -7
