The correct answer for this question is this one: x^2 - sqrt(7) ^ 2

So, how were we able to get that answer.
The question asked us to have an equation of difference of squares.
That means, it is in the form of
a^2 - b^2

Since, the given equation has
x^2 - 7, so we need to have something that is equal to seven

7 = sqrt(7)^2

Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results.

Answer:

IJ = 34

Step-by-step explanation:

Since HK = JK, then IK is a perpendicular bisector and Δ is isosceles, then

IJ = HI , that is

2s = s + 17 ( subtract s from both sides )

s = 17

Then

IJ = 2s = 2 × 17 = 34

Dovator [93]

Answer:

Maria did her job properly. Both gears are perpendicular.

Step-by-step explanation:

Recall that given vectors a and b, they are perpendicular if and only if a\cdot b =0. If a=(a_1,a_2),b=(b_1,b_2). Then a\cdot b = a_1b1_+a_2b_2.

IN our case a=(5,-1,2) and b) (1,-3,-4). So,

a\cdot b = 5\cdot 1 + (-1)\cdot(-3) + 2\cdot(-4) = 5+3-8 =0

So both gears are perpendicular.
