Answer:
Step-by-step explanation:
hello :
2x² + 25 = -x² + 10x
2x²+x²-10x+25 =0
3x²-10x+25=0
∆ = b²- 4ac a=3 and b=-10 and c=25
∆ = (-10)²- 4(3)(25)=100 -300 = -200< 0
two complex solutions
Answer:
a=7.14yd
Step-by-step explanation:
process same as in above question
The side AB is equal to the side DE. Then the value of x is 6.
<h3>What is the triangle?</h3>
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
Triangle ABC is congruent to triangle DEF.
If DE = 41, EF = 23, DF = 36, and AB = 8x − 7.
Then the side AB is equal to the side DE.
AB = DE
8x - 7 = 41
8x = 48
x = 6
Then the value of x is 6.

N^4 - 1 = (n^2 - 1)(n^2 + 1)
= (n + 1)(n - 1)(n^2 + 1)
M-5-(-12) would equal m+7 because there is a negative before the parentheses and in the parentheses which means you would change it to a positive so, negative 5 plus positive 12 is 7 and since the 7 is positive you would add m (hope this helped)
