Answer:

28 + x

Step-by-step explanation:

To write this as an expression, you need to find out what sign you need to use ( multiplication, division,etc.)

More than means to add so you are using an addition sign. Now you need a variable to represent the number.

You can pick any letter but for this I am using x. When you put that all together you get the expression, 28 + x.

Of the following integers, which is the closest approximation to (2âˆš+5âˆš)2(2+5)2?A. 7B. 10C. 13D. 15E. 17

MAXImum [283]

Answer:

C. 13

Step-by-step explanation:

from on online source, the question should be placed as thus:

Of the following integers, which is the closest approximation to (√2 + √5)^2 ?

A. 7

B. 10

C. 13

D. 15

E. 17

This is known as Algebraic expression. So we have to expand to simplify further

using this identity th (a+b)^2 = a^2 + b^2 +2ab

(√2 + √5)^2 =

(√2 + √5)(√2 + √5)

................Expansion of the above

$\sqrt{2}* \sqrt{2} +\sqrt{2}* \sqrt{5} +\sqrt{2} *\sqrt{5}+\sqrt{5} *\sqrt{5}$

2 + 5 + 2√10

~ 2 +5 + 2(3)

C. 13

What is the measure for the following ∠? m∠EOD 20 120 140

Eddi Din [679]

Answer:

Part 1) m∠EOD=20°

Part 2) m∠AOD=80°

Step-by-step explanation:

Part 1) Find the measure of angle EOD

we know that °

m∠EOD=m∠EOX-m∠DOX

we have

Observing the figure

m∠EOX=140°

m∠DOX=120°

substitute

m∠EOD=140°-120°=20°

Part 2) Find the measure of angle AOD

we know that °

m∠AOD=m∠DOX-m∠AOX

we have

Observing the figure

m∠AOX=40°

m∠DOX=120°

substitute

m∠AOD=120°-40°=80°
