Answer:

Step-by-step explanation:

Point E partitions both the x-distance and the y-distance in the ratio 2 : 1. That is, for either the x-coordinates or the y-coordinates, ...

CE : ED = 2 : 1

Try the answers with the x-coordinates.

CE : ED = (1 -(-1)) : (5 - 1) = 2 : 4 . . . . incorrect

CE : ED = (-3 -(-1)) : (5 -(-3)) = -2 : 8 . . . . incorrect

CE : ED = (3 -(-1)) : (5 -3) = 4 : 2 = 2 : 1 . . . . correct

CE : ED = (-1 -(-1)) : (5 -(-1)) = 0 : 6 . . . . incorrect

The only viable choice is (3, 3).

_____

Alternate solution

For a partitioning of m : n, the desired point is ...

E = (n×C +m×D)/(m+n)

For partitioning of 2 : 1, the desired point is ...

E = (1×(-1, -3) + 2×(5, 6))/(2+1) = (-1+10, -3 +12)/3

E = (3, 3)

Factorize the following: 49x² - 25

creativ13 [48]

Answer:

(7x+5)(7x-5)

Step-by-step explanation:

We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.

Trent writes p^2 + 30 = (p + 30)(p + 0) Do you agree with Trent? Explain why

Bingel [31]

Answer:

Statement expressed by Trent is RIGHT.

$(p^2 + 30) = (p+30)(p +0)$

Step-by-step explanation:

Here, the given expression is:

( to show) : $(p^2 + 30) = (p+30)(p +0)$

Now, as we know by DISTRIBUTIVE PROPERTY:

A (B + C) = AB + AC

Consider the RHS of the expression:

(p +30)(p+0) = (p +30)(p) ............ ( a + 0 = a for all a)

Simplifying (p +30)(p) by distributive property, we get:

$(p +30)(p) = p(p) + 30(p) \\= p^2 + 30p\\\implies (p+30)(p+0) = p^2 + 30p$

⇒ Left side = Right side

Hence, statement expressed by Trent is RIGHT.
