X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4
Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.
Answer:
B.x>4is a required interval.
What is the question that you are asking? Do you need to write an equation?
180
Step-by-step explanation:
9:40
?:800
9×20=180
40×20=800
it is a ratio. 9 oranges to 40 people. 40 times 20 is 800 so you do the same to 9 (which gives you 180)
Answer:
Solution given;
<M=5x+10
<R=55
<M+<R=90°
<u>5</u><u>x</u><u>+</u><u>1</u><u>0</u><u>+</u><u>5</u><u>5</u><u>=</u><u>9</u><u>0</u><u>°</u><u>[</u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>equation</u><u>]</u>
