If a = - 1, b = 2 , c = 0 , find the value of 2 a² + 6 - 2 b + 4c

4

Step-by-step explanation:

Plug in the values to the expression and solve:

2a² + 6 - 2 b + 4c

2(-1)² + 6 - 2(2) + 4(0)

Solve:

2(-1)² + 6 - 2(2) + 4(0)

2(1) + 6 - 2(2) + 4(0)

2 + 6 - 2(2) + 4(0)

2 + 6 - 4 + 4(0)

2 + 6 - 4

8 - 4

4

Your final answer would be 4.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
