Discussion:

(d+5) ( d-5) = d^2 - 25 so the answer is (d+5) or choice D

Thank you,

Answer:

The correct answer is Option C . d -5

Step-by-step explanation:

Identity: (a + b)(a - b) = a² - b²it is given that,

it is given that,

(d - 5)(?) = d² - 25

LHS = (d - 5)(?)

RHS = d² - 25

we can compare this with the identity.

here, a = d and b = 5

therefore we can write and start with RHS

RHS = d² - 25 = d² - 5² = (d +5)(d - 5) = LHS

(d +5)(d - 5) = d² - 25

Therefore option C. (d- 5) is the correct answer.

Answer:

you have to do

92×98=9016

then 9016=10(here we roud to 1 signification figure)

49×138=6762

6762=6

216×876=189216

189216=1

After drawing the line y = 2x − 1 and marking the point A = (−2, 7), Kendall is trying to decide which point on the line is clos

igor_vitrenko [27]

Answer:

Step-by-step explanation:

Having drawn the line, Kendall must verify that the point P belongs to the line y = 2x-1 and then calculate the distance between A-P and verify if it is the closest to A or there is another one of the line

Having the point P(3,5) substitue x to verify y

y=2*(3)-1=6-1=5 (3,5)

Now if the angle formed by A and P is 90º it means that it is the closest point, otherwise that point must be found

$d_{AP}=\sqrt{(y_{2}-y_{1})^{2}+(x_{2}-x_{1})^{2}}=\sqrt{(5-7)^{2}+(3-(-2}))^{2}}=\\\sqrt{(-2)^{2}+(5)^{2}}=\sqrt{29}$

and we found the distance PQ and QA

; $d_{PQ}=\sqrt{125}$ , $d_{QA}=12$

be the APQ triangle we must find <APQ through the cosine law (graph 2).
