what's the answer to 4{-4(3-12)-17}?

76

Step-by-step explanation:

4{-4(3-12)-17}

We need to use PEMDAS starting from the inside parentheses out

3-12 = -9

Replace the inside parentheses

4{-4(-9)-17}

Now we work the brackets, using PEMDAS

We need to multiply and divide inside the brackets

{-4(-9)-17}

36 -17

Now subtract

19

Now we replace  the brackets

4*19

Do the final multiplication

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
