Alguem me ajuda a como resolver essa questão -(1+1-4)=?

2

Step-by-step explanation:

-(1+1-4) = ?

comenza con resolviendo lo que está entre paréntesis

1 + 1 y después de restar 4

Ahora tu tienes -(-2) cual es -1 multiplicado por -2

cuando multiplicas dos negativos juntos obtienes un positivo

-1 x -2 = 2

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
