8x + 4 = 44
What is x?

Test

Answers

Answer 1
Answer: Because :

 rearrange 8 × x +  4 - (44) = 0 

Step one: 8x - 40 = 8 × ( x - 5)

Step 2 : Solve 8 = 0 

Step 2 (part 2) : Solve  x - 5 = 0

So, your answer would be x= 5
Answer 2
Answer: 8x = 44 -4
8x = 40
x = 40/8
x = 5

How many​ flowers, spaced every 3 ​in., are needed to surround a circular garden with a 150​-ft ​radius? Use 3.14 for pi.

Answers

The flowers needed to surround a ciruclar garden is 314.

What are the number of flowers needed?

The first step is to determine the cirucmference of the garden. The circumference is the distance round the garden.

Circumference = 2πr

2 x 3.14 x 150 = 942

Now divide the circumference of the garden by 3

942/3 = 314

How do you find the area of a square? No matter its height (length) or bass (width)? ; (

Answers

The general formula for working out the area of a square is:

A (area) = w (width) × h (height).

Or, because a square has equal sides, you can just do:

A = a^(2) (a = side).

The straight line with equation y = 11x - 28
is a tangent to the curve
y = {x}^(3) - a {x}^(2) + bx - 1
at the point (3,5). Find A, the coefficient of
{x}^(2)
​

Answers

Answer:

a=3

Step-by-step explanation:

The equation of the curve is

y=x^3-ax^2+bx-1.

The gradient function is given by

(dy)/(dx)=3x^2-2ax+b

The gradient of this curve at the point (3,5) is equal to the gradient of the tangent y=11x-28 which is 11.

\Rightarrow 11=3(3)^2-2a(3)+b

\Rightarrow 11=27-6a+b

\Rightarrow b-6a=-16...(1)

The given point, (3,5) also satisfies the equation of the curve.

\Rightarrow 3^3-a(3)^2+b(3)-1=5

\Rightarrow 27-9a+3b-1=5

\Rightarrow3b-9a=-21

\Rightarrow b-3a=-7...(2)

Equation (2) minus equation (1) gives

-3a+6a=-7+16

3a=9

This implies that;

a=3

The commonalities between the two are 2^2, meaning you can eliminate 4 from both the numerator and denominator. Dividing them by 4, makes the new fraction 9/20
