Answer:

If those two line on the side of -27 are there purposefully then they mean absolute value and so that would be positive 27 and on a number line the numbers to the right are greater than the ones on the left

So |-27| is GREATER than -45

Answer:

A and D are equal

Step-by-step explanation:

Given

$A=-2[-6, 4, 3 ,7, 12, 10]$

$B=3[-2, 2, 8, 8, 5, 6]$

$3C=3[-2, 8, 2, 5, 8, 6]$

$D=-1[-12, 8, 6, 14, 24, 20].$

Required

The equal matrices

First, we simplify the given expressions

$A=-2[-6, 4, 3 ,7, 12, 10]$

Open bracket

$A= [12, -8, -6 ,-14, -24, -20]$

Next:

$B=3[-2, 2, 8, 8, 5, 6]$

Open bracket

$B=[-6, 6, 24, 24, 15, 18]$

Next:

$3C=3[-2, 8, 2, 5, 8, 6]$

Divide by 3

$C=[-2, 8, 2, 5, 8, 6]$

Lastly:

$D=-1[-12, 8, 6, 14, 24, 20].$

Open bracket

$D=[12, -8, -6, -14, -24, -20].$

By comparison:

$A = D=[12, -8, -6, -14, -24, -20].$

1.18. A fish tank has a base, B, with an area, in square inches, modeled by B(x) = 2x + 6x + 4.

Alekssandra [29.7K]

Answer:

The volume of fish tank is $V(x)=2x^3+12x^2+22x+12$

Step-by-step explanation:

Area of Base of fish tank = $Length \times Breadth$

We are given that A fish tank has a base, B, with an area, in square inches, modeled by $B(x) = 2x^2 + 6x + 4.$

So, $Length \times Breadth =2x^2 + 6x + 4.$

Height of tank = x+3

Volume of tank = $Length \times Breadth \times Height$

So, Volume of tank = $(2x^2 + 6x + 4)(x+3)$

Volume of Tank = $2x^3+6x^2+4x+6x^2+18x+12=2x^3+12x^2+22x+12$

Hence The volume of fish tank is $V(x)=2x^3+12x^2+22x+12$
