Answer:
1. 8
2. 4
3a. -6 and -4
3b. -1/2 and -5
Step-by-step explanation:
3a explanation:
Factor x^2+10x+24
(x+4)(x+6)
Set the factors equal to 0
x + 4 = 0
x + 6 = 0
-4 and -6
3b.
Factor left side of equation.
(2x+1)(x+5)=0
Set factors equal to 0.
2x + 1 = 0 or
x + 5 = 0
x = −1/2
x = -5
-5 and -1/2
Answer:
0
Step-by-step explanation
well at least thats my guess!
we have to go by bidmas. so you substitute first!
so its going to be: 3(-1)(4(-1)+5)+3
all I did is that I replaced all p's by -1 and then you multiply it!
so its gonna be: -3(-4+5)+3
you first solve what's in the brackets which is -4+5 so the answer is 1 like this: -3(1)+3 now its much simpler. all we have to do is to expand the bracket so its going to be -3+3 so the answer is 0!
Answer:
a10 = 12/7
Step-by-step explanation:
an = a1 + (n-1) d
a10 = 3/7 + ( 10-1) 1/7
a10 = 3/7 + (9) 1/7
a10 = 3/7 + 9/7
a10 = 12/7
I’m pretty sure angles 1,3,6 are all 59°
Answer:
ΔABC ~ ΔEDF; x = r × w/z
Step-by-step explanation:
m∠ABC = 180 -47 - 62 =71 = m∠EDF
ΔABC ~ ΔEDF
w/z = x/r
x = r × w/z
