Answer:
(x+4)(x-3) or A
Step-by-step explanation:
I'm going to assume that you meant to write x² and not x2
which means we have
x²+x-12
and we need to factor this
to do this we need two numbers that add up to 1 (b) but mulitply to -12 (a*c)
our two numbers are
4, -3
Which means the answer is
(x+4)(x-3)

Opt A.) is the answer6. Solve for x in each of the following equations:
a. m(x + n) =n
b. x( a + b) = b(c - x)
c. mx = n(m + x)
Step-by-step explanation:
m(x + n) = n
mx + mn = n
mx = n - mn
x = (n - mn)/m
x(a + b) = b(c - x)
ax + bx = bc - bx
ax + bx + bx = bc
x(a + b + b) = bc
x(a + 2b) = bc
x = bc/(a + 2b)
mx = n(m + x)
mx = mn+ nx
mx - nx = mn
x(m - n) = mn
x = mn/(m-n)

What is the value of x?
Answer:
16
Step-by-step explanation:
By the property of intersecting chords inside the circle, we have:
[tex](5x - 7) \degree = \frac{1}{2} (119 \degree + 27 \degree) \\ \\ (5x - 7) \degree = \frac{1}{2} \times 146 \degree\\ \\ (5x - 7) \degree = 73\degree \\ \\ 5x - 7 = 73 \\ \\ 5x = 73 + 7 \\ \\ 5x = 80 \\ \\ x = \frac{80}{5} \\ \\ x = 16[/tex]

What is the perimeter?
Answer: 12km
Step-by-step explanation:
To find the missing side you need to use the formula a^2 + b^2 = c^2 where C is your hypotenuse.
So your formula would be 4^2 + 3^2 = c^2 ...
16 + 9 = c^2
25 = c^2 so square root both sides. Your missing side is 5km and then add all sides together to find your perimeter.
simplify and find each side

X = 4.47 Y = 8.94
Step-by-step explanation:
2[tex]\sqrt{5}[/tex]= 2.23606798
2.23606798 x 2 = 4.47213596
-------
4.47213596
4.47213596^2 + 4.47213596^2 = 8.94427192^2
8.94427192^2 = 80
Square root of 80 is 8.94
Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?
Answer:

Step-by-step explanation:
x+x-5=43
2x=48
x=24
K=24
B=21
Answer:
24
Step-by-step explanation:
So the only way I think would be possible to get the answer is if you divide 43 by 2 (since Bobbie and Kylie are 2 people) then subtract 5 to get the answer?

1. If DC is an angle bisector, what is the
measure of DCB?
2. Without constructing, will the incenter lie
inside or outside this triangle? Why or why
not?
Answer:
1.
∠DCB is the half of the measure of ∠ACB as the angle bisector DC cut it in two equal parts.
m∠DCB = 1/2m∠ACB m∠DCB = 1/2(101.31°) = 50.655°2.
The incenter is the intersection of the angle bisectors.
All three angle bisectors lie inside the triangle, hence the incenter is always inside.

Qual o raio de uma superfície esférica com 40 cm2 de área, em cm, aproximada às centésimas? Responde à seguinte questão, escrevendo apenas o valor numérico em algarismos
Responder:
1,78 cm
Explicación paso a paso:
El área de superficie total de la superficie esférica se expresa como;
T = 4πr² donde
r es el radio
Dado
TSA = 40 cm²
Sustituir
40 = 4πr²
r² = 40 / 4π
r² = 10 / π
r² = 10 / 3,14
r² = 3,185
r = √3,185
r = 1,78
por lo tanto, el radio de la esfera a la centésima más cercana es 1,78 cm

Which of the following cannot be the lengths of the sides of a triangle?
O 6, 8, 12
O 4,4,6
O 6, 6, 12
O 10, 8, 6
Given:
The sides of a triangles in the options.
To find:
Which of the following cannot be the lengths of the sides of a triangle?
Solution:
In a triangle, the sum of two smaller sides must be greater than the longest side, otherwise it cannot be the lengths of the sides of a triangle.
For option A,
[tex]6+8=14>12[/tex]
For option B,
[tex]4+4=8>12[/tex]
For option C,
[tex]6+6=12[/tex]
Here the sum of two smaller sides is not greater than the longest side. So, the sides 6, 6, 12 cannot be the lengths of the sides of a triangle.
For option D,
[tex]6+8=14>10[/tex]
Therefore, the correct option is C.

Q3.
Bill's weight decreases from 64.8 kg to 59.3 kg.
Calculate the percentage decrease in Bill's weight.
Give your answer correct to 3 significant figures.
Answer:
8.48%
Step-by-step explanation:
Bill's weight decreases from 64.8 kg to 59.3 kg.
We need to find the percentage decrease in Bill's weight. It can be calculated as follows :
[tex]\%=\dfrac{64.8 -59.3 }{64.8 }\times 100\\\\=8.48\%[/tex]
So, the required decrease in percentage is 8.48%.
Find the area of the parallelogram below.
The formula for finding the area of a parallelogram is Base x height
A = Bh
In this case the base (the longest side) is 8 cm and the height (distance between the obtuse angle and the base) is 5 cm
A = 8 * 5
A = 40 cm²
Hope this helps!
~Just a girl in love with Shawn Mendes
Answer: 40cm²
The formula is Base × Height. We can find the area if we multiply the Base and Height.
A = Bh
As for that, the Base is the upper length, which is 8 and the height is the obtuse angle inside the parallelogram, which is 5.
Since we got our lengths, we can solve.
Remember how I said the formula is A = Bh. (Area = Base × Height)
So, we can multiply 8 by 5 to get the area.
8 times 5 will equal 40.
Hence, 40cm² is the answer.
find the solution to the following system of equations using substitution or elimination
Answer:
D. (2,-3)
Step-by-step explanation:
if you substitute 2 for the x value and -3 for the y value in both equations, it works out.
instead of y=3x-9 it would be -3=3(2)-9.
you solve and get -3=-3, so it's a solution.
and instead of y=-2x+1 it would be -3=2(2)+1. after solving it, you would get -3=-3 again, so it works for both equations.

A pair of pants originally cost 25 dollars but costs 45 dollars. what is the percent markup? Please help!
Answer:
The markup formula is as follows: markup = 100 * profit / cost .
Step-by-step explanation:
For example if your cost is $10.00 and you wish to markup that price by 40%, 100% + 40% = 140%. Multiply the $10.00 cost by 140% and get the retail price of $14.00.
How do you calculate a 45 markup?
Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.
