Answer: x=−3 or x=13
Step-by-step explanation:
Step 1: Subtract 39 from both sides.
x2−10x−39=39−39
x2−10x−39=0
Step 2: Factor left side of equation.
(x+3)(x−13)=0
Step 3: Set factors equal to 0.
x+3=0 or x−13=0
x=−3 or x=13

Kimani says that the slope of the line between points B and C is greater than the slope of the line between points A and B .
Kiara says that the slope of the line between points B and C is the same as the slope of the line between points A and B.
Answer:
Kiara is correct
.............
Kiara says that the slope of the line between points B and C is the same as the slope of the line between points A and B is Correct.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
From the figure
Slope between A and B = rise/ run 3/3 = 1
and, slope between B and C = 5/5 = 1
So, the slope between A and B is same as the slope between B and C.
Hence, Kiara has correct statement.

the length of a rectangle is represented by 5x - 7 and its width by 3x + 2. find its dimensions of the perimeter is 70 inches
Answer:
l = 18
w = 17
Step-by-step explanation:
2(5x-7) + 2(3x+2) = 70
x = 5
5(5)-7= 18
3(5) + 2 = 17
Answer:
Step-by-step explanation:
we have a rectangle, and the perimeter P=70
P=2L+2W
P=2(5x-7)+2(3x+2)=10x-14+6x+4=16x-10
16x-10=70
16x=70+10=80
16x=80
x=5
L=25-7=18
w=15+2=17

Which of the following expressions always represents how many more votes the winner received than the loser?
A. w - v
B.∣w−v∣
C.None of above
Answer:
[w-v] b is answer
Step-by-step explanation:
How many more votes the winner received than the loser can be thought of as the distance between the two numbers of votes on the number line.
Hint #22 / 5
The distance between two numbers is equal to the absolute value of their difference.
For example, | a - b|∣a−b∣vertical bar, a, minus, b, vertical bar is the distance between aaa and bbb.
Hint #33 / 5

What is the total cost with sales tax price $17.95 tax 6%
Answer:
$19.03
Step-by-step explanation:
Okay, this is a standard percentage problem, so learning how to do this is necessary. First, we have to find what 6% of $17.95 is, since of is our keyword and that means to multiply, and percentages turn into decimals:
17.95 x 0.06 = 1.08
So we have our tax, then we have to add that to our original price to get the whole thing:
17.95 + 1.08 = 19.03
So the total sale price is $19.03

Answer:
Price of one pound of mercury
[tex]x=\$ 2.06[/tex]
Price of one cubic inch of mercury
[tex]z=\$1.0[/tex]
Step-by-step explanation:
From the question we are told that
Mass of mercury [tex]M= 76pound[/tex]
Price of 76 pound [tex]P=\$162[/tex]
Density of mercury is [tex]\rho=13.534 g/cm3.[/tex]
Generally the cost of one pound of Mercury x will mathematically be given as

Step-by-step explanation:
All you really have to do is multiply 1/5 and 3/4. We can separate her backyard in 5 equal parts. In one of those parts, we have her garden, and we break it down into 4 pieces, and make three of those tomato gardens. Now if we break all 5 parts of her backyard into 4 pieces, we can double check our answer, and see that there are 20 pieces, but only 3 have tomatoes. Of course, that's only to double check, but you could also use this method as a model.
