proof:
statements reasons
1.in ∆VXW and ∆BDC, 1.
i.VW=BD(S) i.given
ii.VX=CD(S) ii.given
iii.XW=BC(S) iii.given
2.∆VXW and∆BDC 2.using S.S.S axiom

hence proved.
Answer: there are 50 humans and 24 horses.
Step-by-step explanation:
Let x represent the number of humans in the horse racing area.
Let y represent the number of horses in the horse racing area.
He counted 74 heads. A human has one head and a horse also has one head. It means that
x + y = 74
He counted 196 legs. A human has 2 legs and a horse has 4 legs. It means that
2x + 4y = 196 - - - - - - - -- - -1
Substituting x = 74 - y into equation 1, it becomes
2(74 - y) + 4y = 196
148 - 2y + 4y = 196
- 2y + 4y = 196 - 148
2y = 48
y = 48/2 = 24
x = 74 - y = 74 - 24
x = 50
Answer:
x=-4 and x=4
Step-by-step explanation:
|x|= 4
the lines surrounding x means the x is positive and negative.
so
-x=4 and x=4
x=-4 and x=4
Answer:
sqroot(9) - 7 = -4
sqroot(10) - 7 = -3.838
sqroot(11) - 7 = -3.683
sqroot(12) - 7 = -3.536
It isd not equal to -4 but pretty close so I am thinking that B is the right choice.
Answer is B
