-4=-1b-(1/3)b
-4=-(4/3)b
-4/-(4/3)=b
b=3
-------------------------------
(1/2)3+(5/3)2
3/6+10/6=13/6
-23/3=13/6a
(-23/3)/(13/6)=a
a=-46/13
92
given 2a² + 5b²
substitute given values for a and b into the expression
2(- 6)² + 5(2)² = (2 × 36 ) + (5 × 4) = 72 + 20 = 92
5 10 15 20 25 30 35 40 45 50 55 60 64 70 75 80 85 90 95 100, 105 110 115 120 125 130 (135) 150 155 160 165 170 (175)
Five multiplied each number.
Hope I helped!
