Answer:
−38
First do 10-16 which is -6
(7)(−6)+8/2
=−42+8/2
8/2 equals 4 so add -42 to 4
=−42+4
=−38
So evaluate/subsitue
the equation becomes
(78 times 91+42)^2

do what's inside the parenthasees first
start over
parenthasees
exponents
multiplication and division yes 78 times 91
addition and subtraction so
78 times 91 is first
78 times 91=7098
addition
(7098+42)^2
(7140)^2
restart
parentasees simplified
exponents
7140^2=50,979,600
Answer:
12x⁴ - 15x³ + 18x²
Step-by-step explanation:
1. distribute -3x²
-3x² • 5x = -15x³
-3x² • -4x² = 12x⁴
-3x² • -6 = 18x²
2. combine terms and put in descending order (standard form)
12x⁴ - 15x³ + 18x²
Answer: X= -7
Step-by-step explanation: A negative time a negative is a positive so -12x-7 is equal to 84. 84 plus 16 is equal too 100.
