X^2-8x+21
=x^2-2(4)(x) +16+5
=(x-4)^2+5
here a=1
h=4
k=5
Answer:
x= 12
Step-by-step explanation:
Here we have vertical angles, this means that they are angles that are across from each other on vertical lines. So, they equal each other.
The equation would be: 60= 5x
The only step is to divide 5 to both sides of the equation.
<u>60</u>= <u>5x</u>
5 5
x= 12
Answer:
37.5 hrs
Step-by-step explanation:
You do cross multiplication hours on top and weeks on the bottom.
C=2b
d=c+7
b+c=57⇒b+2b=57⇒3b=57⇒ b=19, c=2*19=38, d=38+7=45
thats given
lets find if there is an x such that d-x=b+x=c⇔ 43-x=19+x=38
43-x=38⇒x=43-38=5
19+x=38⇒x=19
there is no single x (cant be both 5 and 19)
so, i think dan was incorrect.
Personally i like animal crossing and anime
