<h3><u>The value of x is equal to 2.</u></h3>
4(x + 1) = 12(3 - x)
<em><u>Distributive property on both sides.</u></em>
4x + 4 = 36 - 12x
<em><u>Add 12x to both sides.</u></em>
16x + 4 = 36
<em><u>Subtract both sides by 4.</u></em>
16x = 32
<em><u>Divide both sides by 16.</u></em>
x = 2
Answer:
x >= 74
Step-by-step explanation:
x/10 (* 10) + 6 >= 8 (* 10)
x + 6 (- 6) >= 80 (- 6)
x >= 74
(x+b/2a)^2-(b^2-4ac)/2a=0
Step 2:
Re-write the expression:
(x+b/2a)^2=(b^2-4ac)/4a^2
Step 3:
get the square root of both sides:
x+b/2a=sqrt[(b^2-4ac)/4a^2]
Step 4:
Simplifying we get:
x+b/2a=sqrt[b^2-4ac]/2a
Step 5
Make x the subject:
x=-b/2a+/-sqrt[b^2-4ac]/2a
The answer is 21.5 because 7-3 is 4 so 43 divided 4 is 10.75 so 10.75 times 2 is 21.5
