Answer:

2x^{2} - y^{2} +5xy - 2y

A) 4 terms

B) 0 negatives

Step-by-step explanation:

Combine the like terms

So -3x squared + 5x squared = 2x squared

2y squared - 3y squared = -1y squared

There is only one term with 5xy so you leave it as it is

There is only one term with 2y so you leave it as it is

Now put this in an equation and use the negative and positive signs as addition or subtraction signs.

So it looks like:

2x^{2} - y^{2} +5xy - 2y

Given a line segment that contains the points A,B, & C in order, if AB = x + 12, and BC = 2x - 4, and AC = 26, find x.
Troyanec [42]

Answer:

x = 6

Step-by-step explanation:

If A, B and C lies on a straight line in order, then;

AB+BC = AC

x+12+2x-4 = 26

x+2x+12-4 =26

3x+8 = 26

3x = 26-8

3x = 18

x = 18/3

x = 6

Hence the value of x is 6

Sally is 1 year older than 3 times the age of joe.Chirs is 5 years younger than 6 times the age of joe.If sally and Chris are th
Sav [38]
S = sally C = Chris J = Joe
sally is one year older than 3 times the age of joe, so
s = 3j + 1
chris is 5 years younger than 6 times the age of jo, so
c = 6j - 5
sally and chris are the same age so
s = c so
3j + 1 = 6j - 5
-3j -3j
1 = 3j - 5
+5 +5
6 = 3j or
3j = 6
3j/3 = 6/3
j = 2

check
s = c
3(2) +1 = 6(2) - 5
6 + 1 = 12 - 5
