So the tree is 40 ft and then the shadow is 30 so then do 40 -30 = 10 ft difference so then for the second tree do 20 + 10 = 30 ft because the 10 ft difference so the answer is 30 ft tall
What is it that I am supposed to be doing?
Answer: x =3
Step-by-step explanation:
2× 3 = 6
length= 5 inches
width= 2×3= 6 inches
2(l+w) = 2(5+6)
2(11)
2×11= 22
hope this helps:-)
Answer:
The answer is D
(x=3, y=8)
Step-by-step explanation:
We want to reduce as many variable as we can so, we can obtain the value for the remaining variables.
Therefore, the first equation y=x+5 multiply it -2., you have -2y=-2x-10 and sum it to the second (2y-x=13), you will obtain the following: -x=13-2x-10.
You have x=3.
If you substitute x=3 in the first equation, you have y=8
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
