You will need to use FOIL for this, or distribute.
So you will multiply -7y and 5y, then -7y and 3
Multiply 2 and 5y, then 2 and 3
You will get: -35y²-21+10y+6
Combine like terms:
-35y²+10y-15
There you go!
I’m not positive but I think you would go 9x9x4 because it could be 1-9 for the first and third and 2,4,6 or 8 for the second
Pretty sure is 44km. At least i think so
Answer:
1. The correct options are 2 and 4.
2. The measure of angle 6 is 60°.
Step-by-step explanation:
1.
It is given that a∥b , and c is not parallel to a or b. So, we can not establish any relationship among the angles on the line a,b and angles on the line c.
If a traversal line intersect two parallel line, then corresponding angles, alternate exterior angle and alternate interior angles are equal.
Therefore correct options are 2 and 4.
2.
It is given that AB∥CD and m∠3=120°.
Statements Reasons
m∥nm∠1=120° Given
∠5≅∠1 Corresponding angles are equal
m∠5=m∠1 Angle Congruence Postulate
m∠5=120° Substitution Property of Equality
m∠6+m∠5=180° Supplementary angle property
m∠6+120°=180° Substitution Property of Equality
m∠6=60° Subtraction Property of Equality
Therefore the measure of angle 6 is 60°.
