Answer:

4. 10mn - 35m

5. 8rs - 2r² + 16r

6. -4 (y +2)

7. -5p (p - 6q)

Step-by-step explanation:

For number four you basically times 5m to 2n and since it has different variables it would be 10mn ( keep the letters in alphabetical order) , then 5m times negative 7 would be '-35m'

For number five, it wants you to pass through the sign so negative times a negative always gives a positive so '-2r' times '-4s' would equal to '8rs', then -2r times r gives out -2r² since remember there are two same variables-in this case it is 'r' so to show there is two 'r' you put 'r squared' which is 'r²' and negative times a positive value gives negative.

For number 6, you take the Highest common factor out of the two values and in number 6 it would be -4 since there is a factor of -4 in both '-4' and '-8'. So if you take the -4 out of the bracket, there would be 'y' left and also '+2' since there is already a negative outside the bracket.

For number 7, similar to 6, take out the GCF/HCF which is -5 as it is factors in both of them. So -5 out of the bracket then 'p²' would be left and also if you divide 30 by -5 it would give -6 so the remainder would be -6pq. But if you see, you might notice there is both p in two of them so you can also take the p out with -5.

I know this is pretty long but if you don't understand have a read through them and if you still don't get please tell me what I did wrong. Thx

Answer: x = 11

Step-by-step explanation:

2x+5 = 3x-6

2x-3x = -6-5

-x = -11

x = 11

Double-check:
11*2= 22                   11*3=33

22+5 = 27                33-6= 27

How do I do this Q11
SashulF [63]
Look at one of the vertices of the heptagon where two squares meet. The angles within the squares are both of measure 90 degrees, so together they make up 180 degrees.

All the angles at one vertex must clearly add up to 360 degrees. If the angles from the squares contribute a total of 180 degrees, then the two remaining angles (the interior angle of the heptagon and the marked angle) must also be supplementary and add to 180 degrees. This means we can treat the marked angles as exterior angles to the corresponding interior angle.

Finally, we know that for any convex polygon, the exterior angles (the angles that supplement the interior angles of the polygon) all add to 360 degrees (recall the exterior angle sum theorem). This means all the marked angles sum to 360 degrees as well, so the answer is B.

Angles T and V are country that angle T has a measure of (2X +10) angle B has a measure of 48° what is the value of X
enyata [817]
If T and V are complementary angles, their sum is 90°.

   V + T = 90°
   48° + (2X+10)° = 90° . . . . . . . substitute given information
   2X + 58 = 90 . . . . . . . . . . . . .. collect terms
   2X = 32 . . . . . . . . . . . . . . . . .. subtract 58
   X = 16 . . . . . . . . . . . . . . . . . .. divide by 2

The value of X is 16.
