The highest power is 2.
Explanation:
Because x has a maximum power of 2, there will be 2 answers. if it were 3, there could be up to 3 answers, etc.
While solving this problem, you gather all terms on one side so the equation looks like
x
2
−
81
+
17
=
0
x
2
−
64
=
0
then factor
(
x
−
8
)
(
x
+
8
)
=
0
then, because any number times 0 equals 0, we know that one of the two parts in the parenthesis must be equal to 0, so
x
−
8
=
0
or
x
+
8
=
0
and so the two answers
x
=
8
,
−
8
come to be.
Hello from MrBillDoesMath!
Answer: It is part of an arithmetic progression
Discussion:
143 - 125 = 18
125 - 107 = 18
107 - 89 = 18
The value 18 is subtracted from each term in the arithmetic sequence.

Answer: 4
Step-by-step explanation: 1) You need to first understand the question and a way to do that is to list plainly the information given.
2) Let the number be (X)
3) For the equation from the first sentence given; 3(9x-1)
4) From the second sentence; 7(7+2x)
5) Equating both sentences together, since the question says they are the same 3(9x-1) = 7(7+2x)
6) Opening the bracket/expanding the equation.... 27x-3=49+14x
Solving further we will have 13x = 52
X= 52/13
= 4
Answer:
m<ABC=94°
m<BCD=25°
m<ACB=43°
Step-by-step explanation:
To find <mBCD
m<ABD=133°, so m<CBD=133° too.
A triangle is equal to 180°.
22°+133°=155°
80°-155°=25°
To find <mACB
You first need to know triangle ACD measurements.
m<ADC=44° (22°+22°)
Then you take the two 25 and add them.
25°+25°=50°
50°+44°=94°
180°-94°=86°
86°÷2=43°
To find m<ABC
43°+43°=86°
180°-86°=94°
