99 points daniel expanded the expression as shown. -2(-8x-4y+3/4) = -10x -8y- 1 1/4. what errors did he make? check all that apply.

a.the first term should be positive.

b.the second term should be positive.

c.he did not distribute the -2 properly.

d.he added -8 and -2 instead of multiplying -8 by -2.

f.the last term should be -1 1/2, not -1 1/4

answer and step-by-step explanation:

our expression is

-2(-8x-4y+3/4)

to simplify this, we will use the distributive property.   this says we multiply each term inside parentheses by the number outside, -2:

-2(-8x)-2(-4y)-2(3/4)

the first term will be -2(-8x) = 16x.   daniel added the two instead of multiplying.

the second term will be -2(-4y) = 8y.   daniel mistakenly wrote a negative 8y instead of positive.

the third term will be -2(3/4) = -6/4 = -1 1/2.   daniel made a mistake while multiplying and wrote that the answer would be -1 1/4.
