Answer:
The roots are {-5, 7/3}.
Step-by-step explanation:
I am assuming you want to solve this for x.
3x^2 + 8x = 35
3x^2 + 8x - 35 = 0 Try factoring by the 'ac' method.
ac = 3 * -35 = - 105.
We need 2 numbers whose product is -105 and whose sum = + 8.
These are +15 and - 7, so we write:
3x^2 + 15x - 7x - 35 = 0 Now factor by grouping:
3x(x + 5) -7(x + 5) = 0 (x + 5) is common so:
(3x - 7)(x + 5) = 0
The roots are {-5, 7/3}.
The incomplete portion is
Angles _____1_________ are congruent by the Alternate Interior Angles Theorem. Angles _____2_________ are congruent by the Corresponding Angles Theorem.
1) <PBC and <BAD
2) <BAT and <CDA
Angles <PBC and <BAD are congruent by the Alternate Interior Angles Theorem. Angles <BAT and <CDA are congruent by the Corresponding Angles Theorem.
<PBC and <BAD are the Alternate Interior Angles of parallel lines AD and BC and traversal is AP
<BAT and <CDA are the Alternate Interior Angles of parallel lines AB and CD and traversal is TD

it is equivalent to 180-128 because its the same as the angle under route 2
and above runway 2
Answer:
the first one must be 39.5 and the other 42.5
Step-by-step explanation:
multiply 35 by 6 and subtract 32 x 4 you are left with 82. Divide that by 2 and make the difference 3.
