0 = 2x^2 + 5x -3
0 = (2x-1)*(x+3)
2x-1=0 and x+3=0
X= 1/2 and x = -3
Y= 2(0)^2 + 5(0) - 3
Y = -3
Answer:
P = 3 or P = 5/3
Step-by-step explanation:
3p^2 -14p + 15 ➡ (3p - 5) • (p - 3)
Side makes 846 because side = area to the power of 2
Answer:
8 and 9
Step-by-step explanation:
Answer:
jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct
Step-by-step explanation:
so, all angles of a triangle have to add up to 180;
(15x) + (8x - 11) + (3x + 9) = 180
15x + 8x - 11 + 3x + 9 = 180
add your common numbers
26x - 2 = 180
add 2
26x = 182
divide 26
x = 7
put it back into the equation
15(7) + 8(7) - 11 + 3(7) + 9 = 180
180 = 180
