Divide each term in the bracket by 4:

−

Explanation:

Multiplying by

is the same as dividing by 4. - You are finding a quarter of something.

To find a quarter of the bracket, divide each coefficient by 4.

You will get two unlike terms so you will not be able to simplify them.

This is the reason why you cannot simplify inside the original bracket either.

Step-by-step explanation:

An actor invests some money at 8% simple interest, and $21 comma 000 more than four times the amount at 10% simple interest.

Dennis_Churaev [7]

Answer:

First investment = $98000

Second = $413,000

Step-by-step explanation:

Given the following :

Investment 1:

Let first investment = f

Rate = 8% = 0.08

Investment 2:

$21,000 more than 4 times of investment 1:

4f + 21000

Rate = 10% = 0.1

Total annual interest earned from both :

$49,140

Interest on investment 1 + interest on investment 2 = $49,140

To solve:

Simple Interest = principal * rate * time

Time = 1 year

Total interest = (f * 0.08 * 1) + ((4f + 21000) * 0.1 * 1)

49140 = 0.08f + 0.4f + 2100

0.48f = 47040

f = 47040 / 0.48

f = 98000 = first investment

Second investment :

4f + 21000

= 4(98000) + 21000

= $413,000

How do you write 50,679 in expanded form

Alika [10]

Answer: 50,000 + 600 + 70 + 9, or, which is equivalent, 5×10,000 + 6×100 + 7×10 + 9; either is considered in expanded form.

Explanation:

The expanded form of a number is the same number written as the sum of each digit according to its place value.

I will explain you in detail using your number: 50,679.

i) The digit 5 is in the then thousands place, the 0 is in the thousands place, the 6 is in the hundreds place, the 7 is in the tens place, and the 9 is in the ones place.

ii) So:

5 represents 50,000, or 5 ×10,000;

6 represents 600, or 6×100;

7 represents 70, or 7×10; and

9 represents 9, or 9×1.

ii) Then, the expanded form is the representation of the number as the sum of those values, which is:

50,000 + 600 + 70 + 9, or

5×10,000 + 6×100 + 7×10 + 9×1.

Will give brainliest please help ASAP

marissa [1.9K]

Answer: 1) If we talk about whole numbers then we should choose only square numbers that could be the area of square so that if we want to find its side so we a can find its square root i.e. side.

2) We can find the square root of the area of the given square to find the side length of the square.

3) No , it is not possible to find a side length that would be perfect for a square with an area of 45 square units because if we find its side we need to find its square root i.e.

$side=\sqrt{45}=\sqrt{3\times3\times5}=3 \sqrt{5}$ ................>which is irrational and √5=2.236

∴side=3×2.236=6.708 unit ......> which is not accurate we need to take approx value of it to get the side length of the square.
