Answer:

f all his animals were pigs, there'd be 880 legs, There are 240 legs missing which represents 120 chickens (so he has 220 - 120 100 pigs.)

Check: (120 x 2) + (100 x 4) = 240 + 400 = 640 QED

IrinaVladis [17]

Answer:

The midpoint of a line segment joining (a, b) and (c,d) is given by the formula (\frac{a+c}{2},\frac{b+d}{2} )

Step-by-step explanation:

If point <em>M </em>in the figure lies midway between points P(x_{1},y_{1}) and Q(x_{2},y_{2}), point <em>M</em> is called the midpoint of segment. To find the coordinates of <em>M</em>, we average the x-coordinates and average the y-coordinates of P and Q.

So the the midpoint of the line segment with endpoints at (a,b) and (c,d) is the point with coordinates of

(\frac{a+c}{2},\frac{b+d}{2} )

Help please, kind of confused
Anvisha [2.4K]

Answer:

Step-by-step explanation:

Yikes. This is quite a doozy, so pay attention. We will begin by factoring by grouping. Group the first 2 terms together into a set of parenthesis, and  likewise with the last 2 terms:

(2d^4+6d^3)-(18d^2-54d) and factor out what's common in each set of parenthesis:

2d^3(d+3)-18d(d+3). Now you can what's common is the (d + 3), so factor that out now:

(d+3)(2d^3-18d) BUT in that second set of parenthesis, we can still find things common in both terms, so we continue to factor that set of parenthesis, carrying with us the (d + 3):

(d+3)2d(d^2-9) BUT that second set of parenthesis is the difference of perfect squares, so we continue factoring, carrying with us all the other stuff we have already factored:

(d+3)2d(d+3)(d-3). That's completely factored, but it's not completely simplified. Notice we have 2 terms that are identical: (d + 3):

2d(d+3)^2(d-3) is the completely factored and simplified answer, choice 3)

Help please. . PT= x+2, TR=y, QT+2x, TS=y .
Brut [27]

This is a trial and error answer.

Suppose that QT = -3, then

x + 2 = y

2x = y + 3

Apply substitution,

2x = (x+2) + 3

2x = x + 5

x = 5

y = 7

chek your answer,

x + 2 = y
