For determining the correct degree of a polynomial, you need to look at each term and find the degree by adding the exponents of each variable in it. The largest degree is the degree of the polynomial.
Classification by the number of terms:
monomial<span> (1 term)
</span>binomial<span> (2 terms)
</span>trinomial<span> (3 terms)
</span>polynomial (<span>four or more terms</span>).
Answer:
x = 4, y = 8
Step-by-step explanation:
If the triangles are congruent by the HL Theorem, it means that the hypotenuse and one leg of the right triangle are congruent to the corresponding one leg and hypotenuse of the other.
Thus;
2x - 5 = y - 5 (Eqn 1) and
y - 3 = x + 1 (Eqn 2)
Thus:
Rewrite equation 1
2x = y - 5 + 5
2x = y
Substitute y = 2x in equation 2.
y - 3 = x + 1 (Eqn 2)
2x - 3 = x + 1
Collect like terms
2x - x = 3 + 1
x = 4
Substitute x = 4 in equation 1
2x - 5 = y - 5 (eqn 1)
2(4) - 5 = y - 5
8 - 5 = y - 5
3 = y - 5
3 + 5 = y
8 = y
y = 8
Answer: b = 14/3 = 4.667 feet
The decimal value is approximate. In reality the 6's go on forever. Round that however you need to.
================================================
Work Shown:
b = unknown base
h = height = 6 ft
A = area = 14 sq ft
A = b*h/2
14 = b*6/2
14 = b*3
14 = 3b
3b = 14
b = 14/3
This approximates to 14/3 = 4.667 ft
Answer:
a=200;110;101andb=decreasing
Step-by-step explanation:
a.(100×10+1000)/10=200
(100×100+1000)/100=110
(100×1000+1000)/1000=101
