Answer:
31.5cm²
Step-by-step explanation:
area of a triangle =1/2 b h
b= 7cm
h=9cm
 1/2×7×9
= 1/2×63
= 31.5cm²
hypotenuse is unknown so,
c²=a²+b²
c²= 7² + 9²
 = 49 + 81
 c²= 130
c= 11.4cm
perimeter= 7 +9+11.4
 =27.4cm

Given:
Let x be the whole amount inherited.
1/2 * x - invested with Bernie Madoff
1/3 * x - lost due to identity theft
1/8 * x - lost in casino
40,000 - remainder
x - x/2 - x/3 - x/8 = 40,000
LCM: 
2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24
3: 3, 6, 9, 12, 15, 18, 21, 24
8: 8, 16, 24, 
   x * 24/24 = 24x / 24
x/2 * 12/12 = 12x / 24
x/3 *   8/8   = 8x / 24
x/8 *   3/3   = 3x / 24
40,000 * 24/24 = 960,000 / 24
24x/24 - 12x/24 - 8x/24 - 3x/24 = 960,000/24
(24x - 12x - 8x - 3x)/24 = 960,000/24
x/24 = 960,000/24
24 * x/24 = 24 * 960,000/24
x = 960,000
x = 960,000 initial inheritance
x/2 = 960,000/2 = 480,000 invested with Bernie Madoff
x/3 = 960,000/3 = 320,000 lost due to identity theft
x/8 = 960,000/8 = 120,000 lost in the casino
40,000 - remaining amount.
960k - 480k - 320k - 120k = 40k
40k = 40k

              ❖ A number y increased by 5 is at least -21.

           ❖ First, if you come across the word "increased" it means we 
     "increase" a number, or add something to that number, like
y increased by 5  
 
Now, we are also given that this expression is at least -21, which means it can't be -21; it can be -21 or it can be greater than -21.
So we have

<em>Solving for y</em>
<em></em>
-    Subtract 5 on both sides:-


So the values of y greater than or equal to -26 will make this inequality true.

Answer:
3/20, -3/10
Step-by-step explanation:
Its a quadratic equation, use the quadratic formula. (-b+- )/2a
)/2a
20x^2+3x-2=0
(-3+- )/40
)/40
(-3+-9)/40
So you get 6/40=3/20 and -12/40=-3/10
