5√x+3 = -20
÷5. : √x+3 = -4
square: x+3 = 16
-3: x = 13
√x+18 -2 = x -4
+2 : √x+18 = x -2
square: x+18 = x^2 - 4x +4
-18: x = x^2 -4x -14
-x : 0 = x^2 -5x - 14
foil: (x- 7) (x+2) = 0
x = 7, -2

In a television commercial, the manufacturer of a toothpaste claims that more than four out of five dentists recommend the ingredients in its product. To test that claim, a consumer-protection group randomly sampled 400 dentists and asked each dentist whether they would recommend the ingredients in the manufacturer's toothpaste. 334 of the 400 dentists responded that they would recommend the ingredients in the manufacturer's toothpaste. Can the consumer-protection group conclude that the manufacturer's claim is true

If we multiply a number by 5, then we add it by 3.5, and we divide the result by 2, and from the new result we subtract 7.6 we obtain 6.65. Find out the number.
Answers
Answer:
the number is 5
Step-by-step explanation:
((n x 5 + 3.5) ÷ 2) -7.6 = 6.65
( 5n + 3.5) ÷ 2 = 14.25
5n + 3.5 = 28.5
5n = 25
n = 5

Find the equation parallel to y = -x - 5 and passing through (-3, -3)
Answers
Answer:
y = -x - 6
Step-by-step explanation:
If it's parallel, then it means that the slope will remain the same. The slope is
-1.
To find the y-intercept, you need to plug the coordinates into the equation,
y = -1x + b
-3 = -1(-3) + b
-3 = 3 +b
-6 = b
The equation is y = -x - 6

Complete the function for this graph:
Answers
Answer:
The equation is:
f(x) = Ix + 3I - 2
Step-by-step explanation:
For a function like:
f(x) = Ix - kI + c
k is the x-value where the vertex is, and c is the y-value where the vertex is.
In the graph we can see that the vertex is in the point (-3, -2)
then:
x-value = -3 = k
y-value = -2 = c
Replacing those in the equation for the function:
f(x) = Ix - (-3)I - 2
f(x) = Ix + 3I - 2

Rhombus L M N O is shown. Diagonals are drawn from point L to point N and from point M to point O and intersect at point P. The length of L M is 3 x minus 3 and the length of M N is x + 7. What is the perimeter of rhombus LMNO? 20 units 24 units 40 units 48 units
Answers
Answer:
48units
Step-by-step explanation:
Find the diagram of the rhombus attached
From the diagram, LM = MN
Hence;
3x - 3 = x + 7
Find x
Add 3 to both sides
3x - 3 + 3 = x + 7 + 3
3x = x + 10
3x - x = 10
2x = 10
x = 10/2
x = 5
LM= 3x - 3
LM = 3(5) - 3
LM = 12
Since LM = MN, then MN = 12
Since all the sides of the rhombus are equal then;
Perimeter of the rhombus = LM + MN + NO + OL
Perimeter of the rhombus = 12 + 12 +1 2 + 12
Perimeter of the rhombus = 48units
Answer:
48 Units is the answer
