Answer:
8.−2x^2+6x
9.y-1
Step-by-step explanation:
8.(−2x)(x−3)
=(−2x)(x+−3)
=(−2x)(x)+(−2x)(−3)
=−2x^2+6x
9. y^2−y
y
= y^2−y
y
=y−1
Answer:
-36,047.
Step-by-step explanation:
Sum of n terms = a1 .( r^n - 1) / (r - 1)
So Sum of 7 terms = -11 . ((-4)^7 - 1 / (-4-1)
= -11 * -16,385 / -5
= -36,047.
<h3><em>A = p(1+r/n)nt
</em></h3><h3><em>A = final amount
</em></h3><h3><em>p = principal = 2000
</em></h3><h3><em>r = interest rate = .04
</em></h3><h3><em>n = # times compounded pet year = 2
</em></h3><h3><em>t = time in years = 7
</em></h3><h3><em> </em></h3><h3><em>A = 2000(1+.04/2)2(7)
</em></h3><h3><em>A = 2000(1.02)14
</em></h3><h3><em>A= 2638.957</em></h3><h3><em>HOPE IT HELPS.....</em></h3>
Answer:
x = -4/17
Step-by-step explanation:
<h3>1)x=180°−(50°+60°) x = 180 ° - ( 50 ° + 60 ° ) =180°−110°=70°</h3>
<h3>2)x=180°−(30°+90°) Since it is a right angle so the third angle is a right angle. ...</h3>
<h3>3)x=180°−(30°+110°) x = 180 ° - ( 30 ° + 110 ° ) =180°−140°=40°.</h3>
<h3>4)Here; 50°+2x=180° Or, 2x=180°−50°=130° ...</h3>
<h3>5)This is an equilateral triangle. ...</h3>
<h3>6)This is a right angled triangle.</h3>
