The 18 "distributes" through each of the parentheses,

multiplying by each of the terms inside.

So we have 18(4x) + 18(8) which simplifies to 72x + 144.

Factor completely 4xy − 7x + 20y − 35.
kati45 [8]

Answer:

A) (x+5)(4y-7)

Step-by-step explanation:

Given expression:

4xy-7x+20y-35

To factor the given expression completely.

Solution:

In order to factor the expression, we will factor in pairs.

(4xy-7x)+(20y-35)

We will factor the G.C.F of the terms in the pairs.

G.C.F. of 4xy and 7x can be given as:

4xy=4.x.y

-7x=7.x

Thus, G.C.F. = x

G.C.F. of 20y and 35 can be given as:

20y=2\times 2 \times 5.y

35=5\times 7

Thus, G.C.F. = 5

The expression after factoring the G.C.F. pairs is given as:

x(4y-7)+5(4y-7)

Taking G.C.F. of the whole expression as (4y-7) is a common term.

(x+5)(4y-7)

The expression is completely factored.

Find the volume of a pyramid with a square base, where the perimeter of the
lianna [129]

Answer:

42.7\,\,cubic\,\, meters

Step-by-step explanation:

Given: Perimeter of base of a pyramid = 12.8 m

Height of the pyramid = 12.5 m

To find: volume of a pyramid

Solution:

Perimeter of base of a pyramid = 12.8 m

As base of the pyramid is a square,

12.8 = 4(side\,\,of\,\,a\,\,square)

side of a square = \frac{12.8}{4}=3.2\,\,m

Area of a square (A) = (side\,\,of\,\,a\,\,square)^2=(3.2)^2=10.24\,\,m^2

Height of the pyramid (h) = 12.5 m

Volume of the pyramid = \frac{Ah}{3}=\frac{1}{3}(10.24)(12.5)=42.7\,\,cubic \,\,meters
