Steps to solve for the zero:
(x + 7)(x + 5) = 0
~Set both factors to equal zero
x + 7 = 0
x + 5 = 0
~Solve for x in [ x + 7 = 0 ]
x + 7 = 0
x + 7 - 7 = 0 - 7
x = -7
~Solve for x in [ x + 5 = 0 ]
x + 5 = 0
x + 5 - 5 = 0 - 5
x = -5
Therefore, the solutions are x = -7 and x = -5
Best of Luck!

Dan earns £352 over the course of a five-day week. How much is that per day?
Answer:70.4
Step-by-step explanation:
Dan earns 352 over 5 days.
To see how much he earns in 1 day, we can divide 352 by 5.
352/5=70.4 so he earns 70.40 everyday

Step-by-step explanation:
The reciprocal of the cosine is the ___.
A. secant
B. tangent
C. sine
D. cotangent
Answer:
The correct answer is A
Step-by-step explanation:
The secant is the distance from the center to the vertical tangent in a certain direction.
Answer:
A. secant
Step-by-step explanation:
For trigonometric ratios, we know that cosine is [tex]\frac{adjacent}{hypotenuse}[/tex]. The reciprocal of something is just flipped over. So the reciprocal of cosine is [tex]\frac{hypotenuse}{adjacent}[/tex], which is the ratio for secant.
Another way we can remember this is [tex]sec x = \frac{1}{cos x} \\\\cos x = \frac{1}{sec x}[/tex]
The area of a garden is 30 square feet. The perimeter is 26 feet. What are the measurements of each side?
Answer:
So there are two possibilities:
x = 3, y = 10
x = 10, y = 3
Step-by-step explanation:
Make two equations:
Length = x
Width = y
xy = 30
2x + 2y = 26
You can simplify the second equation to:
x + y = 13
x = 13 - y
(13 - y) * y = 30
13y - y^2 = 30
y^2 - 13y + 30 = 0
Factor:
(y - 3)(y - 10) = 0
y = 3, y = 10
So there are two possibilities:
x = 3, y = 10
x = 10, y = 3
Which two values are greater than 3/5

Emma great grandparents lived in a log cabin with their 3 children. The log cabin had a floor area of 450 square feet. The ceiling is only 7 feet hight. What is the volumr of the log cabin
Answer:
The volume is 3150ft³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, cuboid
Given data
Area =450 ft²
Height h =7ft
We know that the volume of a cuboid
Volume = length x width x height
Volume =lbh
Volume = area x height
Volume = 450*7= 3150ft³

Determine whether the pair of actions results in independent or dependent events. Serena picks one marble out of a bag. Then, after replacing the marble, she picks another marble.
A) Dependent; the 1st marble selection will affect the 2nd marble selection.
B) Independent; the 1st marble selection will not affect the 2nd marble selection.
C) Dependent; the 1st marble selection will not affect the 2nd marble selection.
D) Independent; the 1st marble selection will affect the 2nd marble selection.
Please help!
Answer:
B) Independent; the 1st marble selection will not affect the 2nd marble selection.
Step-by-step explanation:
When finding the probability of events in mathematics, we have both independent and dependent events.
Independent events are events that occur when the results of selection of the first events does not affect the results or outcomes of the second events.
Dependent events are the opposite of Independent events. They are events that occur when the results or outcomes obtained from the second events is affected by the results or outcomes from the selection of the first events.
From the question, we can see that the first event is she picked one marble from the bag. The second event is she replaced the marble before picking another marble. By doing this, the total number of possible outcomes for the probabilities of both events remains the same and they are unaffected.
Therefore, we can say that the two events are Independent because the 1st marble selection will not affect the 2nd marble selection.
Answer:
B) Independent; the 1st marble selection will not affect the 2nd marble selection.Step-by-step explanation:
These events are independent, because Serena replaced the marble which doesn't alter the total number of outcomes to determine the probability of picking another marble.
Therefore, the right asnwer is B.
Remember that independent events are defined as those which don't influence in each other probabilities.

Median?
Mode?
Mean?
Range?
Answer:
Median: 75
Mode: 50
Mean: ≈ 75.4
Range: 50
Step-by-step explanation:
Median:Arrange the numbers in order:
50, 50, 70, 80, 88, 90, 100
There is no exact middle number.
[tex]70 + 80 = 150\\150/2 = 75[/tex]
The median is about 75.
Mode:50, 50, 70, 80, 88, 90, 100
"50" appears the most.
The mode is 50.
Mean:Add all numbers in the set.
[tex]100+88+50+50+90+70+80 = 528[/tex]
Divide by the number of values in the set.
[tex]528/7 = 75.4285714286[/tex]
75.4285714286 ≈ 75.4
The mean is about 75.4.
Range:Subtract the smallest number in the data set from the largest number in the data set.
