If 16+4x is 10 more than 14, what is the value of 8x?

Answers

16 + 4x = 10 + 14

16 + 4x = 24.

4x = 24 - 16

4x = 8

x = 8 ÷ 4

x = 2

8x = 2 × 8

8x = 16

Final answer = 16.

Final answer:

To find the value of 8x, first solve the equation 16 + 4x = 14 + 10 by isolating the term with 4x. The value of x is found to be 5. Substituting the value of x into 8x gives the answer of 40.

Explanation:

To find the value of 8x, we need to first solve the equation 16 + 4x = 14 + 10. First, we subtract 14 from both sides to isolate the term with 4x. This gives us 16 + 4x - 14 = 14 + 10 - 14. Simplifying, we have 4x + 2 = 24. Next, we subtract 2 from both sides to isolate 4x. This results in 4x = 22. Finally, we divide both sides by 4 to find the value of x, which is 5. Now, we can substitute the value of x into the expression 8x to find the answer.  8x = 8(5) = 40.

Step-by-step explanation:

After plotting the data where x equals the length of the side of a polygon, and f(x) represents the area of the polygon, Jack used technology and determined the appropriate model to approximate the area of the polygon, f(x) = x2 + 2x + 3. Use the model Jack created to predict the area of a polygon that has a side length of 3.10

The area of polygon is 18 sq. units.

What is polygon?

In geometry, a polygon is any closed curve made up of a collection of continuous line segments, without any intersections. Triangles (three sides), quadrilaterals (four sides), and pentagons.

Given that jack has a model f(x) = x² + 2x +3

where f(x) is area of polygon and x shows length of side

area when length is 3

substitute value of x in equation

f(x) = x² + 2x +3

f(3) = 3² + 2ₓ3 + 3

f(3) = 9 + 6+ 3

f(3) = 18

Hence area of polygon according to given equation is 18 sq. units

We are given the model to approximate the are of the polygon to be
f(x) = x² + 2x + 3
where x is the length of the side
For a polygon with a side length of 3, x = 3
f(3) = 3² + 2(3) + 3
f(3) = 18
The area is 18

dunno wat last part is but since they all equal e
a+2=b-2=2c=d/2
I am guessing that a+b+c+d=45 such that a+2=b-2=2c=d/2

make in terms of one thing
let's do a

a+2=b-2
a+4=b

a+2=2c

a+2=d/2
2(a+2)=d

mult both sides by 2

sub back

a+4=b, 8+4=b=12

(a+2)/2=c, (8+2)/2=10/2=c=5

2(a+2)=d, 2(8+2)=2(10)=d=20






a=8
