Cho hình thang ABCD có AB//CD và góc A=góc D =90 độ và AD=CD=2AB, E là điểm đối xứng với A qua B . A)Cm 1/2 AE=AB và tứ giác AECD là hình vuông. B) Gọi M là trung điểm của EC ,I là trung điểm của BC và DM .Cm diện tích tam giác DIC=diên tích tứ giác EBIM

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.

ok so what's the question?

step-by-step explanation:

b: y = 2x + 2

step-by-step explanation:

y = 2x + 1

we want a line that is parallel, so it will have the same slope

the line is in the form y= mx+b, so the slope is 2

we have a slope and the y intercept (0,2)

since x is 0 we know the y point which is the y intercept

we can use y= mx+b to write the equation of the line

m is the slope and b is the y intercept

y = 2x +2
