Answer:
-24
Step-by-step explanation:
Given expression:
3z (2y - 4)²
z = -2 and y = 3
To solve this problem, simply substitute:
3z (2y - 4)² = 3(-2){2(3) - 4}²
= -6(6-4)²
= -6 (2)²
= -6 x 4
= -24
Answer:
-15 and -2
Step-by-step explanation:
Since a negative times a negative equals a positive, but when added, still stays a negative, the factors must both be negative.
Negative Factors of 30:
-30 + -1 = -31
-15 + -2 = -17
-10 + -3 = -13
-6 + -5 = -11
The two factors of 30 that add up to -17 are -15 and -2.
Hope this helps. Have a nice day.

Answer:
The estimated weight is in the range:
75.6 pounds
Weight
92.4 pounds
Step-by-step explanation:
Since, the maximum error is 10%.
Therefore, the maximum and minimum vales will be 10% more and 10% less than 84 pounds, respectively.
<u>For Maximum Limit</u>:
= (1.1)(84 pounds)
= <u>92.4 pounds</u>
<u>For Minimum Limit</u>:
= (0.9)(84 pounds)
= <u>75.6 pounds</u>
Hence, the estimated weight is in the range:
75.6 pounds
Weight
92.4 pounds
