Answer:
For a polynomial of the form ax²+bx+c, rewrite the middle term as a sum of two terms whose product is a⋅c = 8⋅ −3=−24 and whose sum is b=−2.
8t²+4t−6t−3
Factor out the greatest common factor from each group.
4t(2t+1)−3(2t+1)
Factor the polynomial by factoring out the greatest common factor, 2t+1.
(2t+1)(4t−3)
Step-by-step explanation:
The answer is C. If you simplify the ratios in the table, they equal 3:5. You look at the examples, and divide both numbers in the ratios by this simplified porpotion. If the numbers are the smame as eachother after dividing, that is how you know your answer
Answer:
A
Step-by-step explanation:
Let the length of one side of the square be x
x^2 = 7/9
x = sr(7/9) = 0.881917...
The total length of the fence = 4 x 0.881917... = 3.528 miles to 4 s.f.
