Answer:Simplificando
5 (2j + 3 + j) = 0
Reordene os termos:
5 (3 + 2j + j) = 0
Combine termos semelhantes: 2j + j = 3j
5 (3 + 3j) = 0
(3 * 5 + 3j * 5) = 0
(15 + 15j) = 0
Resolvendo
15 + 15j = 0
a verdadeira questão é por que o vizinho de Sarah quer dentes de tubarão
Step-by-step explanation:
Mova todos os termos contendo j para a esquerda, todos os outros termos para a direita.
Adicione '-15' a cada lado da equação.
15 + -15 + 15j = 0 + -15
Combine termos semelhantes: 15 + -15 = 0
0 + 15j = 0 + -15
15j = 0 + -15
Combine termos semelhantes: 0 + -15 = -15
15j = -15
Divida cada lado por '15'.
j = -1
Simplificando
j = -1
Tubarão ou cação é um tipo de peixe de esqueleto cartilaginoso e um corpo hidrodinâmico (com exceção dos Squatiniformes, Hexanchiformes e Orectolobiformes)
Answer:
-12
Step-by-step explanation:
So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope(m).
Then, we need to know the slope-intercept form of an equation. The slope intercept form is
where
is the slope of the line and
is the y-intercept. In this problem where can see the second equation is already in this form.
Now that we know we need to find the slope, and we know that the second equation is in slope-intercept form we're going to convert the fist equation into the correct form.
To do this, we know we need to make sure
is the only thing on the left side of the equal sign. Currently, on the left side of the equal sign we have
so we have to divide both sides by
to get 
Now that we have it converted to slope-intercept form, we are going to look for what represents the slope or
in the equation. In this case the slope would be -12, so any line with a slope of -12 will be parallel.
The equation of a circumference is 2

r. Since we know that r=17, we plug that into the formula, and get an answer of C. 34
Answer:
4x² + 20x - 2
Step-by-step explanation:
To evaluate (c ○ d)(x), substitute x = d(x) into c(x)
c(x² + 5x)
= 4(x² + 5x) - 2
= 4x² + 20x - 2
Yes in order for them to be symmetrical they both have to be Symmetrical or the same
