Answer:
c and e because alternate interior angles are congruent
Step-by-step explanation:
Answer: Sum (b) = -4
Product (c) = 4
<u>Step-by-step explanation:</u>
In the quadratic equation ax² + bx + c
- b represents the sum of the roots
- c represents the product of the roots
2x² - 8x + 8 = 0
2(x² - 4x + 4 = 0)

b= -4 c= 4
Step-by-step explanation:
1)
Let x=larger number
y=smaller number
x+y=59
x-y=13
Now adding these two equations we get
2x=72
x=36
Now as x-y=13
y=x-13=36-13=23
y=23
Therefore the larger number is 36 and the smaller number is 23
(or else u could also write)
The numbers are 36 and 23
---------------------------------------------
2)
Let x=first number
y=Second number
x+y=15
2x-y=6
Now adding these two equations we get
3x=21
x=7
Now as x+y=15,
y=15-x=15-7=8
y=8
Therefore the first number is 7 and the second number is 8
-------------------------------------------
3)
Let x=Larger number
y=smaller number
x-y=3
x-3y=-11
Now on subtracting these two equations we get
2y=14
y=7
Now as x-y=3,
x=y+3=7+3=10
x=10
Therefore the larger number is 10 and the smaller number is 7
Answer:
Step-by-step explanation:
nth term = 3n+2
a) first term = 3+2 = 5
Second term = 3(2)+2 = 8
Third term = 3(3) +2 = 11
b) tenth term = 3(10)+2 = 32
