Step-by-step explanation:
estimate the sums and round the numbers to the neares hundred
Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.
Two equivalent fractions to 3/4 are 6/8 and 12/16!
Answer:
b=-19
Step-by-step explanation:
We know that one of the solutions is x=-4/5
That is a solution to x. So if we plug in (-4/5) into the x in the equation, then it should equal 0.
5(-4/5)^2+b(4/5)+12=0
Now, just solve for b.
5(16/25)+b(4/5)+12=0
(16/5)+(4/5)b+12=0
(76/5)+(4/5)b=0
(4/5)b=-(76/5)
b=-19
Answer:
13x^2- 6x - 9
Step-by-step explanation:
Please use the word "subtraction" or "less ... " or similar.
8x^2+x-10 less -5x^2+7x+1 is
8X^2 + x - 10
-(-5x^2+7x+ 1)
-----------------------
13x^2- 6x - 9
