We can do this easily using 0s.
(x - i) (x + i) (x + 4) (x - 1) = 0
If you plug in any of the numbers, you'll get 0, making the equation true.
C all integers also rational numbers
The dimension of the rectangle should be 3x14 cm and 14 cm. Thus, its area is 3x14 cm x 14 cm which is equal to 588 cm². The area of the 3 circles is,
3A = 3πr² = 3π(14 cm/2)² = 147π cm² = 461.81 cm²
The area of the shaded region is the difference between the areas which is equal to 126.19 cm².
Answer:
D
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= , substituting values
= → D
