3x + 1 = 8
move +1 to the other side
sign changes from +1 to -1
3x+1-1= 8-1
3x= 7-1
divide by 3 for both sides to get x by itself
3x/3= 7/3
Answer:
x= 7/3 and x= 2 1/3
Answer:
43
Step-by-step explanation:
we know that ABC and CBD need to add up to 90 so we have
47+CBD=90
CBD=43
Answer:
The answer A
Step-by-step explanation:
B: You need a side that is longer than 2 equal sides. B is incorrect.
A: Try
9^2 + 12^2 = 15^2 if that works, A will work.
81 + 144 = 225
This works. I used these numbers because they were easier to see.
0.9^2 + 1.2^2 = 1.5^2
0.81 + 1.44 = 2.25
2.25 = 2.25
That is the answer A
But we have to check the other two.
C:
0.9^2 = 0.81
1.2^2 = 1.44
1.8^2 = 3.24 This won't work. 3.24 is just too big.
D:
0.9^2 = 0.81
0.6^2 = 0.36
1.5^2 = 2.25 It's too far away.
Answer:
x=1
Step-by-step explanation:
6/12 = x/2
Simplify the left side by dividing the top and bottom by 6
1/2 = x/2
Using cross products
2x =2
Divide by 2
2x/2 =2/2
x=1
The degree of a polynomial is categorized by its highest power of its leading variable.
<h3>Degree and number of terms of a polynomial</h3>
Given the following polynomial functions, we are to classify them based on their degrees and the number of terms
For the polynomial function 5x^4 - 7x + 9
The degree is 4 being quartic and there are three terms in the expression
For the polynomial 2x3 + 3 < 3, the degree is 3 (cubic) with three terms in the expression.
For a Quintic quadnomial, the degree of the polynomial is 5.
