Answer:
14 pulgadas
Step-by-step explanation:
a 7 pulgadas, entonces el diámetro es 2(7) = 14 pulgadas.
First one
20=n/5+10
minus 10 both sides
10=n/5
times 5 both sides
50=n
2.
hmm
expand
p(x)=2x^2+5x+3-3x-3n
p(x)=2x^2+2x+3-3n
it looks like the coefients of the x terms are divisble by 2
because
if we have
p(x)=2(something)
the p(x) is divisible by 2
therefor that factor is 2 or -2
find what value of n works
so
3-3n=a multipule of 2
we are given
-3,-2,0,2
try each
3-3(-3)=3+9=12, that's divisble by 2
3-3(-2)=3+6=9, that's not divisible by 2
3-3(0)=3, that's not divisble by 2
3-3(2)=3-6=3, that's not divisble by 2
the onnly one that woks is when n=-3
answer is A
Answer:
28
Step-by-step explanation:
2x + 3y = 7
Now, since 8/2 is 4 and 12/3 is also 4, we can multiply the entire original equation by four in order to get the equation that we want
4(2x + 3y = 7)
8x + 12y = 28
It’s the second 1 in the top corner , where the u line is perfect and the slanted line is perfect
2 to the 8th power is 256.
It's the same as doing 2x2x2x2x2x2x2x2=256.
