2((x+2)(x+2)}-4=28
2{x^2 + 4x + 4}-4=28
2x^2 +4x=28
2(x^2+2x)=28
x^2+2x=28/2
x^2+2x=14
The absolute value is the value of the number without the sign. So in this case it's 3 and -3
(3x + 5)° + (10x - 7)° = 180°
13x + (-2) = 180
13x = 180 + 2
13x = 182
x = 14
∠QRT = 3 * 14 + 5 = 42 + 5 = 47°
∠TRS = 10 * 14 - 7 = 140 - 7 = 133°
Answer:
10.6 kg
Step-by-step explanation:
first convert 4 4/10 to kg
4/10 is equal to .4
so 4.4kg were rotten
subtract from total
15-4.4=10.6 kg
