What number should be added to both sides to complete the square? x^2 + 8x = 4
son4ous [18]

Answer:

16

Step-by-step explanation:

x² + 8x = 4 ⇔ x² + 8x + 16 = 4 + 16 ⇔ x² + 2×4x + 4² = 20 ⇔ (x + 4)² = (2√5)²

Remark : (2√5)² = 20

Shape A can be transformed to shape B by a reflection in the x-axis followed by a translation (c/d). Find the value of c and the
bagirrra123 [75]

Answer:

c = -6

d = -1

Step-by-step explanation:

Given

See attachment for grid

Required

Find c and d

From the attachment, we have:

a = (3,5) --- Point on A

a' = (-3,-6) --- Corresponding point on B

When A is reflected across the x-axis, the rule is:

(x,y) \to (x,-y)

So, we have:

(3,5) \to (3,-5)

Next, is to calculate the translation from (3,-5) to (-3,-6)

This is calculated using:

3 + c = -3

and

-5 + d = -6

So, we have:

3 + c = -3

c = -3-3

---- i.e. Shift by 6 units to the left

-5 + d = -6

d = 5 - 6

d = -1  --- i.e. Shift by 1 unit down
