Answer:
58 cm^2
Explanation:
there are three rectangles in the shape
the first one on the left has length = 7 cm and width = 3 cm.
so area = l × w
= 7×3
=21 cm^2
the one in the middle has length = 4 cm and width = (7- 3) => 4cm
so area = 4 × 4
= 16 cm^2
the last one to the right is identical to the first, so area = 21 cm^2
The combined area = 21 + 16 + 21
= 58 cm^2
Multiply 5% by 30
0.05*30 = 1.50
$1.50 is 5% of $30

Answer:
D = 141
Step-by-step explanation:
The given quadratic equation is
.
It is required to find the value of the discriminant. The value of discriminant of any quadratic equation is given by :
Here, a = 5, b = 9 and c = -3
On plugging all the values, we get :
So, the value of discriminant for y is 141.
Answer:
3rd term: 24
10th term: 220
Step-by-step explanation:
<em>For the 3rd term</em>
2*3 + 2*(3^2) = 6 + 2*9 = 6 + 18 = 24
<em>For the 10th term</em>
2*10 + 2*(10^2) = 20 + 2*100 = 20 + 200 = 220
