Elan Coil [88]

Answer:

10u^{3}+4u^{2}-2u+10 or 2(5u^{3}+2u^{2}-u+5)

Which phrase matches the algebraic expression below? <br><br> 2(x − 7) + 10
Black_prince [1.1K]

<u>Answer:</u>

Two times the difference of a number x and 7 plus 10.

<u>Step-by-step explanation:</u>

We are to write a phrase which matches the following algebraic expression below:

2 ( x − 7 ) + 1 0

We can see that there is a bracket with a coefficient outside it so we can express it as:

<em>'Two times the difference of a number x and 7'.</em>

While + 10 can be added to it to complete the phrase:

Two times the difference of a number x and 7 plus 10.

galina1969 [7]

Answer:

$ 4096 on the 7th day

Step-by-step explanation:

From the amount earned for the first 3 days it's 1 , 4 , 16 , .... We realize it increases exponentially.

So therefore:

Day 1 =4⁰

Day 2=4¹

Day 3=4²

Day 4=4³

Day 5=4⁴

Day 6=4⁵

Day 7=4⁶

Therefore on day 7 he saves 4⁶ which is $4096
