the required value is 22

The simplified value of  (a−2b)³ is 10648.

What is equation?

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Parts of an Equation

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.

given:

(a−2b)³

and,  a=−2 and b=−12

Now, substituting the values

(a−2b)³

=  ((-2)−2(-12))³

=  (-2 + 24)³

= 22³

= 10648

Hence, the simplified value is 10648.

A) Graph A

B) Graph B

C) Graph C

D) Graph D

I think it’s B I’m not sure about it but I hate wan I gat it wrong.

The graph D has a x-intercept = −1  and y-intercept = 5

How to determine the graph?

The given parameters are:

x-intercept = −1

y-intercept = 5

The above means that the graph crosses the x-axis at -1, and it crosses the y-axis at -5

From the list of options, the graph that satisfies the above highlights is graph D

Hence, the graph D has a x-intercept = −1  and y-intercept = 5

Answers

Answer:

V = 3/8 * 1/8 * 5/8 cm^3 = 15 / 512 cm^3

Since all sides are evenly divisible by 1/8 and v = (1 / 8)^3 = 1 / 512 cm^3

N = V / v = (15 / 512) / (1 / 512) = 15 blocks

Answer:

y=1/2x + 3

Step-by-step explanation:

The first thing you need to know is that the slope of a perpendicular line is the opposite reciprocal of the other slope. Find the slope of this line, which is -2. The opposite reciprocal is 1/2. So, you know that the perpendicular line is equal to y=1/2x. Plug the x coordinate (4) in for x to have: y=1/2(4). Multiply 4 by 1/2 to get y=2. Since the y coordinate is supposed to equal 5, add 3 to y=2 to get 5. Since 3 is the amount we added, thats where the y intercept will be. Hope this helped!

This is important: "the codes are three consecutive integers" That means,

x is code for country A

(x+1) is code for country B

(x+2) is code for country C

whose sum is 81" means

x + (x+1) + (x+2) = 90
