Answer:
C and E
Step-by-step explanation:
Examples of binomials (two terms) :
9a - 5
3x + 6y
-4t + 2
Examples of monomials (one term) :
6x
10z
4a
Examples of trinomials (three terms) :
7y - 3x + 4
8x + 7 - 2a
4x + 9y + 5
(There can also be exponents and fractions in any kind: binomial, monomial, or trinomial.)
A. 2x+y=25; x+y=20
x represents cheese wafers and y represents chocolate wafers.
B. I will choose elimination since there is y and y. I can multiply one equation by -1 to get y and -y, which cancels out.
2x+y=25
-x-y=-20
Add equations
x=5
Plug x in
5+y=20
y=15
Final answer: 5 cheese wafers, 15 chocolate wafers
Answer: BC = 15
Step-by-step explanation:
Since the triangles are congruent, that means they are the same. So side AB = side EF. Since we know side FD is 15, that means side BC= 15
So for this, you'll be using the pythagorean theorem to solve for the height.
Solve the exponents to get
Subtract 81 on each side to get
Square root each side, and your answer should be
or 13.23 ft
