4x² + 2x - 30 = 0
<span>
factor out the GCF:
</span>2(2x² + x - 15) = 0
<span>
factor the trinomial completely:
2x</span>² + x - 15 = 0
2x² + 6x - 5x - 15 = 0
2x(x + 3) - 5(x + 3) = 0
(2x - 5)(x + 3) = 0
<span>use the zero product property and set each factor equal to zero and solve:
2x - 5 = 0 or x + 3 = 0
2x = 5 x = -3
x = 2.5
</span><span>The roots of the function are x=-3, x=2.5</span>
Four hundred-thousand plus sixty-thousand plus five-thousand plus one-hundred.
Answer:
the angle would be 1/2 i did this problem before and got it correct
Step-by-step explanation:
A=LW, we are told that the dimensions are 42 and 48 so:
