Answer:
Step-by-step explanation:a
Answer:
Step-by-step explanation:
4x+y=14
x-2y=8
then;
x=8-2y
substitute;
4(8-2y)+8-2y=14
32-8y+8-2y=14
40-10y=14
26=10y
y=2.6 , work out 4x+2.6=14 to get x
Answer:
Step-by-step explanation:
Since RQT=155
4x-20+3x+14=155
7x-6=155
7x=161
x=23
Answer:
see explanation
Step-by-step explanation:
A monomial is an expression with one term
A binomial is an expression with 2 terms
A trinomial is an expression with 3 terms
Thus
- 2x² - x + 3.5 ← has 3 terms, hence trinomial
10xyz³ ← has 1 term, hence monomial
- x²y² + 2y ← has 2 terms, hence binomial
8x² + 0.25 ← has 2 terms, hence binomial
x³ + 2x²y - 3x ← has 3 terms, hence trinomial
