<h2><em><u>Work:</u></em></h2>

Expand (4√3 − 2√5) (3√10 + 5√6) using the FOIL Method:

<em>Apply the distributive property: </em>

4√3 (3√10 + 5√6 ) − 2 √ 5 ( 3 √ 10 + 5 √ 6 )

4√3 (3√10) + 4√3 (5√6) − 2√5 (3√10 + 5√6)

4√3 (3√10) + 4√3 (5√6 ) − 2√5 (3√10) − 2√5 (5√6)

Simplify and combine like terms:

<u>12√30+60√2−30√2−10√30</u>

<em>Subtract</em> 10√30 from 12√30

2√30+60√2−30√2

<em>Subtract</em> 30√2 from 60√2

2√30+30√2

<h2><em><u>Answer:</u></em></h2>

The result can be shown in multiple forms.

<em>Exact Form:</em>

2√30+30√2

<em>Decimal Form:</em>

m) 2.597= 2 .0+ 0.5+ 0.09+0.007

Step-by-step explanation:

A medida que nos alejamos del punto decimal, el número de ceros aumenta y el dígito se mueve hacia la derecha.

Los valores después del decimal se denominan décimas, centésimas y milésimas.

a) 1.585 =1.0 + 0.5+ 0.08+0.005

b) 1.059= 1 .0+ 0.0+ 0.05+0.009

c) 2.440 = 2.0 + 0.4+ 0.04

d) 5.329= 5.0 + 0.3+ 0.02+0.009

e) 8.801 = 8.0 + 0.8+ 0.00+0.001

f) 9.999= 9.0 + 0.9+ 0.09+0.009

g) 3.718 = 3.0 + 0.7+ 0.01+0.008

h) 6.840= 6.0 + 0.8+ 0.04

i) 7.504 = 7.0 + 0.5 +0.004

j) 5.225 = 5.0 + 0.2+ 0.02+0.005

1) 4.063 = 4.0 + 0.0+ 0.06+0.003= 4+0.06+0.003

m) 2.597= 2 .0+ 0.5+ 0.09+0.007

The values after the decimal are called tenths hundredths and thousandths

You need to order carpet for a room that has a length that is twice its width. if the area of the room is 128 ft 2, find the wid
Setler [38]
A = L * W
L = 2W
A = 128

128 = 2W * W
128 = 2W^2
128/2 = W^2
64 = W^2
sqrt 64 = W
8 = W <== width

L = 2W
L = 2(8)
L = 16 <== length

2z - 6 = 2(2 + 2) - 10
Blababa [14]

Answer:

z=2

Step-by-step explanation:

2z-6=2(2+2)-10  Distribute.

2z-6=4+4-10      Combine like terms.

2z-6=-2              Add 6 on both sides.

   <u>+6 +6</u>

2z=4                   Divide by 2 on both sides.

<u>/2 /2</u>

z=2

Hope this helps! Have a great day ^^
