Which product is negative (-3..7)(1.4) (3...4). ( 3.8)(5.7)(1.4). (-3...4)

Negative times negative is positive.

Positive times positive is positive.

Negative times positive is negative.

(-3.8)(-5.7) gives you a positive product then it is + times (-1.4) which gives you a negative product.

- * -  =   +

- * +   = -

+ * - =  -

The last one is negative

because the first part  is - * - = +

then + * - = -

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
