Answer 1

Answer: -5[4 - (-3)(2)] Given
-5(4 + 6) Multiply -3 by 2. Since you're subtracting the product, -6, it becomes a positive.
-20 - 30 Distribute
-50 Subtract

Remember that when you're doing a problem that has brackets and parentheses, always do the operations on the inside first. For instance, in this problem, you shouldn't distribute 5 before you multiply -3 by 2.

D. 2 sqrt 27

Answers

The correct question will be 3^(3/2) , in words 3 power 3/2
3^(1+1/2)= (3^3)^(1/2)
= 27^(1/2)
so, sqrt 27 is correct answer

What is the simplified form of the quantity of x plus 8, all over the quantity of x plus 2 + the quantity of x minus 3, all over 4?

Answers

Answer: $(x^2+3x+26)/(4x+8)$

Step-by-step explanation:

Since, according to the question the given expression,

$(x+8)/(x+2) + (x-3)/(4)$

= $(4(x+8)+(x-3)(x+2))/(4(x+2))$

= $(4x+32+(x-3)(x+2))/(4x+8)$ (By solving the parenthesis )

= $(4x+32+x(x+2)-3(x+2))/(4x+8)$ ( by distributive property)

= $(4x+32+x^2+2x-3x-6)/(4x+8)$ ( again on applying distributive property)

= $(3x+26+x^2)/(4x+8)$ ( by operating like terms)

= $(x^2+3x+26)/(4x+8)$

$(x + 8)/(x + 2) + (x - 3)/(4) = (4(x + 8))/(4(x + 2)) + ((x + 2)(x - 3))/(4(x + 2)) = (4(x) + 4(8))/(4(x + 2)) + (x(x - 3) + 2(x - 3))/(4(x + 2)) = (4x + 32)/(4(x + 2)) + (x(x) - x(3) + 2(x) - 2(3))/(4(x + 2)) = (4x + 32)/(4(x + 2)) + (x^(2) - 3x + 2x - 6)/(4(x + 2)) = (4x + 32)/(4(x + 2)) + (x^(2) - x - 6)/(4(x + 2)) = ((4x + 32) + (x^(2) - x - 6)/(4(x + 2)) = (x^(2) + (4x - x) + (32 - 6))/(4(x + 2)) = (x^(2) + 3x + 26)/(4(x + 2))$

PLEASE HELP! How do I solve this problem?

Answers

The toughest part of this problem could be deciding what names to give the quantities of one-Euro and two-Euro coins.

-- I called the number of one-Euro coins ' N '.
Each of them is worth 1 Euro, so all ' N ' of them are worth ' N ' Euros.

-- I called the number of two-Euro coins ' T '.
Each of them is worth 2 Euros, so all ' T ' of them are worth ' 2T ' Euros.

-- The total number of coins in Penny's pocket is (N + T), and it says there are 11.

-- Their total value is (N + 2T), and it says the total value is 18.

So now you have two equations, with two unknowns.

   N + 2T = 18
   N + T = 11

Subtract the bottom equation from the top one, and you get:

(N - N) + (2T - T) = (18 - 11)

   T = 7    (there are 7 two-Euro coins in her pocket)

That right there is the answer to the question, so you don't need to go
any farther. But if you wanted to, you could also figure out how many
one-Euro coins there are in her pocket.

What is the correct answer for 20 + 20 × 0 + 1 = ?

Answers

The correct answer for the expression 20 + 20 × 0 + 1 by applying the rule of PEMDAS is equal to 21.

To explain in detail, we follow the order of operations (also known as PEMDAS ) to solve this expression step by step:

Parentheses Exponents Multiplication and Division (from left to right)

Addition and Subtraction (from left to right)

Let's solve the expression step by step:

20 + 20 × 0 + 1

20 + (20 × 0) + 1 [There are no parentheses or brackets]

20 + (0) + 1 [Perform the multiplication first (20 × 0 = 0)]

20 + 0 + 1 [Perform the addition (20 + 0 = 20)]

20 + 1 [Perform the addition (20 + 1 = 21)]

Therefore , the value of the given expression is equal to 21.

The rule is when you don't have parenthesis you need to multiply and divide first from left to right, so

20+ 20x0 +1= 20 + 0 + 1=21

By definition, future value is?

Answers

Answer:

Future value is the value of an item calculated after certain years on a given value at a given certain interest rate.

Future value is always increasing in nature and when future value is decreasing it is know as Depreciate value.

And is calculated using the formula as stated

$FV=P(1+(r)/(100) )^n$

Where P is the principal amount that is the given amount for which we have t calculate the future value.

r is the rate of interest and it is the rate at which the given principal value is increasing.

n is the time period for which the principal value is kept.

Future value is the value of an asset at a specific date. It measures the nominal future sum of money that a given sum of money is "worth" at a specified time in the future assuming a certain interest rate, or more generally, the rate of return; it is the present value multiplied by the accumulation function.
