To organize the expressions according to the number of terms, you should understand what a term is. A term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs. It is organized as follows:
2x2y + x2 - 3x + 4
3x + y + z
x + 2xyz
9x2yz
Answer: The formula is (b1 + b2)h+PH
Step-by-step explanation:
Answer:
Line
intersects line 
Step-by-step explanation:
We are given that
Subtract one equation from other then we get
Substitute the value of x in first equation then we get
Hence, the solution 
is the intersection point of two line equations .
Answer:Line intersects line
ABC=DBC
(This will probably be a way more complex explanation than you need but it’s what I did.)
Okay so you know B=B because they’re both right angles. You know A=D because of the isosceles triangle theorem- if two sides of a triangle are congruent, then the angles opposite those sides are congruent. That leaves C=C. If B=B and A=D and all triangles add up to 180 degrees, C and C need to be the same.
