defon

Answer:

$L=15\ m$

Step-by-step explanation:

we know that

The perimeter of rectangle is equal to

In this problem we have

$P=42\ m$

$W=6\ m$

substitute in the formula and solve for L

$42=2L+2(6)$

simplify

$21=L+(6)$

$L=21-6=15\ m$

What is the volume of this cuboid? Please help me!!!?!

Snowcat [4.5K]

The formula of a volume of a cuboid:

$V=lwh$

l - length

w - width

h - height

We have:

l = (x + 4) cm

w = (x + 1) cm

h = 3 cm

Substitute:

$V=(x+4)(x+1)(3)$ use distributive property

$V=(x+4)(3x+3)$

$V=(x)(3x)+(x)(3)+(4)(3x)+(4)(3)$

$V=3x^2+3x+12x+12$ combine like terms

$\boxed{V=3x^2+15x+12}$

Answer:

total weight in pounds = 22 lb

Step-by-step explanation:

Let's first find out the total weight in kilograms.

total weight = 4 x 2.5 kg = 10 kg

The approximation for kilograms (kg) to pounds (lb) is 1 kg = 2.2 lb.

So if 1 kg is 2.2 lb, 10 kg is 10 times more.

10 kg = 10 x 2.2 lb = 22 lb
