Answer:
8 + 4i
Step-by-step explanation:
according to the bi form, the solution to the expression √4+ √−4+√36 + √−4 would be 8 + 4i
<span> −3|x + 7| = −12
* </span><span> −3(x + 7) = −12
-3x - 21 = -12
-3x = -12 + 21
-3x = 9
x = 9/-3
x = -3
</span>
* −3*[ -(x + 7)] = −12
3x + 21 = -12
3x = -12 -21
3x = -33
x=-33/3
x = -11
answer:
x = -11 and x = -3
D = k + 20
j = 3k - 120
d = j
k + 20 = 3k - 120
20 + 120 = 3k - k
140 = 2k
140/2 = k
70 = k.....so Katie weighs 70 lbs
David and Johnathan each weigh 90 lbs
Though we cannot exactly find PT, we can find it in terms of TQ.
Multiply the second equation by 7/6 to get 7TQ/6=7x-7/3. Subtracting 65/3 from both sides, we get 7TQ/6-65/3=7x-24. Since the right side is equal to PT, PT=7TQ/6-65/3.
