Answer:
It already is in standard form
y=(x-2)(x-4) :)
Step-by-step explanation:
Answer: The missing value, y = 24
Step-by-step explanation:
The triangles are similar, so the sides are proportional.
The length of side BD is 10. The segment AD is also 10. Add them to get the length of side AB.
DE is 12
12:10 = y:20 . 20/10 = 2 2×12 = 24
First of all you have to use the formula
a^2+B^2=c^2
a=6 b=4 c=?
6^2+4^2=?
36+16=?
after you add 36 and 16 find the square root
the square root of 52 is 7.211
if you don't want it in decimals you can just put it like this <span>sqrt(52)</span>
Z-score=(score-mean) standard deviation
test A : z(A)= (90-64)/8=3.25
test B: z(B)= (95-60)/10=35/10=3.5
she did better on test B,
answer is A
