Answer:
(x + 3)² + y² = 16
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 3, 0 ) and r = 4, thus
(x - (- 3))² + (y - 0)² = 4², that is
(x + 3)² + y² = 16
The answer is 42
the equation x2-11+42 means that 7 and 6 added equal 11 but multiplied equal 42
Answer: it gets smaller, 13 times smaller
Step-by-step explanation:
Size of the figure/13
Answer:
4×(x² - 4x + 2)
Step-by-step explanation:
4x2 - 16x + 8 = 4×x² - 4×4×x + 4×2 = 4×(x² - 4×x + 2)
