Faça o estudo do sinal da função y = -4x+16 e indique para que valores de x a função é positiva, negativa ou nula:
a)positiva x>5, negativa x<5 e nula x=5
b)positiva x>-4, negativa x<-4 e nula x=-4
c)positiva x<4, negativa x>4 e nula x=4
d)positiva x<-5, negativa x>-5 e nula x=-5

∠cbe and ∠deb are same-side interior angles.

i took the test

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

i think the answer is a p = 78

step-by-step explanation:

there are 6 sides of a hexagon, multiply 13 x 6
