For the first one EF is 119 degrees now since that's made with two radii it makes a central angle so whatever that arc is the central angle will be the same. fro the second one since SRQ is 52 degrees you just take that and subtract it from 180 to get SQ. I'm not quite sure about the third one. the forth you are taking the measurement of the arc its connected to and dividing that by 2 so it would be 71 degrees. I'm pretty sure in right.

Option D: $(6x-1)(x-1)$ is the product of the expression

Explanation:

The expression is $6(x^{2} -1)\times\frac{6x-1}{6(x+1)}$

We need to determine the product of the expression.

To determine the product of the expression, we need to simplify the given expression.

Thus, we have,

$6(x^{2} -1^2)\times\frac{6x-1}{6(x+1)}$

The term $(x^{2} -1^2)$ is of the form $a^2-b^2$

Now, we shall use the identity, $a^2-b^2=(a+b)(a-b)$

Hence, we have,

$6(x+1)(x-1)\times\frac{6(x-1)}{6(x+1)}$

Multiplying the terms and cancelling the common terms, we get,

$(x-1)\times({6x-1})$

Hence, the product of the given expression is $(6x-1)(x-1)$

Therefore, Option D is the correct answer.

Ede4ka [16]

The pizza place should sell 45 cheese pizza in order to reach daily goal.

Step-by-step explanation:

Let, x=pepperoni pizzas and y= cheese pizzas.

And 15x+12y=540

If pizza place runs out of pepperoni pizza, then x=0 we need to find how many cheese pizza (y) must be sold to achieve the goal.

Putting x=0 and finding y,

$15x+12y=540\\15(0)+12y=540\\12y=540\\y=\frac{540}{12} \\y=45$

So, The pizza place should sell 45 cheese pizza in order to reach daily goal.

Answer:

B (x^2 +4x -2) + (x^2 -2x +4)= 2x^2 +2x +2

Step-by-step explanation:

The blue are positive and the red are negative

The top line is x^2 +4x -2

The second line is x^2 -2x +4

Adding together

x^2 +4x -2 + x^2 -2x +4= 2x^2 +2x +2
