We will use the distributive property. -4 times 9z=-36z -4 times -2=8 so we have -36z+8 as our answer
Answer:
92
Step-by-step explanation:
w=7
x=4
y=8
z=1
8^2 + 2(4) + 3 (7) -1
64 + 2 * 4 + 3 * 7 -1
64 + 8 + 21 - 1
72 + 20
92
(3 + 2i)(5 + i)
15 + 3i + 10i + 2i^2
15 + 13i - 2
13 + 13i
Add 5/9 to both sides. common denominator would be 72 so you would multiply the top and bottom of 3/8 by 9 (bc 9x8 is 72) to get 27/72. you would multiply top and bottom of 5/9 by 8 to get 40/72 and you would add 40+27 which equals 67 so x=67/72 i believe
