Answer: The values of A is -3
Step-by-step explanation:
(x + 6y) − (3x − 10y)
distribute the negative to the second equation
x*-3x=-3x^2
x*10y=10xy
6y*-3x=-18xy
6y*10y=60y^2
take the end terms and create an equation
-3x^2+10xy-18xy+60y^2
combine like terms
<u>-3</u>x^2<u>-8</u>xy+<u>60</u>y^2~ final answer
-3 is the A term
-8 is the B term
60 is the C term
Answer:20--- angle ADB and CDB
21---angles ADE and CDA

no
Answer:
p(x)=20x+300+0.03x^2
p(70)=1553 dollars
2x + 3y = 1470
3y = -2x + 1470
y = -2/3 + 490
g >4
14g>56
Divide each side by 14
14g/14 > 56/14
