How do I solve this
2x2+ 2x2 -2+2x2=

Answers

Use BODMAS, this is the order in which you must
1. Brackets
2. Divide
3. Multiply
4. Add
5. Subtract
therefore 2x2+2x2-2+2x2=10

2x2+ 2x2 -2+2x2=
4 + 4 - 2 + 4 = 10

How do u multiply x^2-4 over x^2-1 times x+1 over x^2+2x

Answers

$(x ^ 2-4 )/(x ^ 2-1)*( x + 1 )/(x ^ 2 +2 x)=(x ^ 2-2^2 )/(x ^ 2-1)*( x + 1 )/(x(x +2 )) =\n \n \n =((x -2)\not(x+2)^1 )/((x -1)\not(x+1)^1)*( \not(x + 1)^1 )/(x\not(x +2)^1 )= ( x-2 )/(x(x-1)) \n \n \n \na^2-b^2 =(a-b)(a+b)$

(X2-4)/(x2-1). * (x+1)/(x2+2x)
[(x-2)(x+2)]/[(x-1)(x+1)]. * (x+1)[x(x+2)]
(x-2)/(x-1) * 1/x
(x-2)/(x2-x)

An object is thrown upward at a speed of 121 feet per second by a machine from a height of 8 feet off the ground. The height h of the object after t seconds can be found using the equation h = -16t^2+121 t+8 When will the height be 17 feet?

When will the object reach the ground?

Answers

17=-16t^2+121t+8
16t^2-121t+9=0
this is a quadratic.
it solves to 7.487seconds and 0.075 seconds.

0=-16t^2+121t+8
16t^2-121t-8=0
this solves to 7.628 and -0.066. obviously the time cant be negative so the only real answer is 7.628 seconds

The slope of the points is closer to 0.5 thus y = 0.5x + 1.2 will be the best approximation thus option (B) is correct.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

As per the given points,

Let's take two-point (1,1) and (2,1.5)

The slope associated with the above points will be as,

(1.5 - 1)/(2 - 1) = 0.5

Thus, the line will be y = 0.5x + 0.3

Hence "The slope of the points is closer to 0.5 thus y = 0.5x + 1.2 will be the best approximation".
