x²-4x-5=0
The given equation is quadratic
So we can perform prime factorisation of it.
factors of -5, that add up to give -4 are -5 and 1
therefore replacing -4x by -5x+x
x²-5x+x-5=0
performing factoring by grouping,
(x²-5x)+(x-5)=0
x(x-5)+(x-5)=0
(x+1)(x-5)=0
x+1=0 and x-5=0
Answer is x=-1 and x=5
could be 17. not sure i´d wait for someone smarter than me to answer.
Answer:
Yes; DEF was produced through rigid transformations.
Step-by-step explanation:
You aren't changing the shape or angles of the triangle, you're just moving it through space.
Answer:
C. 28.6
, 0.28
Step-by-step explanation:
<em><u>To find the white portion's area, you add 44 and 47, then multiply it by π</u></em>
:
44 + 47 = 91
(3.14)
A = 28.574 → A = 28.6
<em><u>There are 7 parts of the circle, and 2 of them are white. So divide 2 by 7:</u></em>
2 ÷ 7 = 0.28
Answer:
That would be 4.
