Answer:

Step-by-step explanation:

To find the answer, multiply 4 and 2 together, since 13 is 2 times less than 26.

Let's double check,

26 ÷ 13 = 2

so,

4 × 2 = 8

Answer:

Please see attached image

Step-by-step explanation:

We can work on the products of binomials using distributive property to multiply every term of the first binomial by every term of the second one. Finally combine like terms to get the trinomial that results:

1) $(2+a)(2+a)=4+2a+2a+a^2=4+4a+a^2$

2) $(2a+1)(2a+1)=4a^2+2a+2a+1=4a^2+4a+1$

3) $(2a-1)(2a-1)=4a^2-2a-2a+1=4a^2-4a+1$

4) $(2-a)(2-a)=4-2a-2a+a^2=4-4a+a^2$

On the 1st of January 2014, Carol invested some money in a bank account. The account pays 2.5% compound interest per year. On th

cluponka [151]

She started with x.
After 1 year, she had 1.025x.
She withdrew £1000, so now she has 1.025x - 1000.
Then it earned interest for 1 year and ended up as 1.025(1.025x - 1000).
The actual amount of money was £23 517.60.
Therefore,

1.025(1.025x - 1000) = 23517.60

1.025x - 1000 = 22 944

1.025x = 23 944

x = 23 360

Her original deposit was £23 360

A submarine cuts through the water at an elevation of 203 meters under the sea. The sub rises, and the elevation changes by 4.3

Natalija [7]

It should be 76.1m under water. First multiple 15x4.3=64.5, and 5.2x12=62.4. Add those together to get 126.9. Subtract that from the initial elevation of 203 and get your answer.
