You would need to facto 2x² + 9x - 35 to get (2x - 5)(x + 7).
We can find this first by dividing the 2x² into 2x and x, which we can put into the brackets:
(2x _ _)(x _ _)
Then we need to find two factors of -35 that have a difference of 9 when one is multiplied by 2, which gives us +7 and -5 as (7 × 2) - 5 = 14 - 5 = 9.
This gives our final answer as:
(2x - 5)(x + 7)
We cannot use foil on this expression as there are no brackets to expand.
I hope this helps!
Answer:
14.4
Step-by-step explanation:
Divide the number satisfied by total people surveyed then multiply by 100 for the percent.
960/2400 = 0.4
0.4 x 100 = 40%
The answer is 40%
Where is the question?? I'll be glad to answer in the comments once the question is given. Hope to hear from you!
To find the total area of the octagon you can find the area of the rectangle that is created by the entire figure and subtract the areas of the four congruent right triangles.
(10 cm x 6 cm) - [4(1/2 x 2 x 2)]
60 cm² -8 cm² = 52 cm²
The total area of the octagon is 52 cm².
