Step-by-step explanation:
This answer has to be 18.
Answer:
See below
Step-by-step explanation:
arrange to standard form (x-h)^2 + (y-k)^2 = r^2 h,k = center r = radius
x^2 - 4x + y^2 + 2y = 4 complete the square for 'x' and 'y'
(x-2)^2 - 4 + (y-1)^2 -1 = 4
(x-2)^2 + ( y-1)^2 = 4 + 4 + 1 = 9 '9' is equal to r^2 so r = 3
<u>center = 2,1 radius = 3 </u>

The value of the first 7 from the left is 70.
If you divide 70 by 10, you get the value of the second seven, 7.
Another way to know this is equivalent fractions:
1/10 = 7/10
10 X 7 = 70
1 X 7 = 7
Answer:
Area of rhombus is 105.84 cm².
Step-by-step explanation:
Area of rhombus is given by
- Area = diagonal ¹ × diagonal ² / 2
- = 8.4 + 8.4 × 6.3 + 6.3 / 2
- = 16.8cm × 12.6 cm /2
- = 211.68 cm²/2
- = 105.84 cm²
