Answer:
7[tex]x^{5}[/tex] + 18x³ + 8x
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
7x³(x² + 2) + 4x(x² + 2) ← distribute both parenthesis
= 7[tex]x^{5}[/tex] + 14x³ + 4x³ + 8x ← collect like terms
= 7[tex]x^{5}[/tex] + 18x³ + 8x
8c = 56
two step equation
Answer: c=7
Step-by-step explanation:
8c = 56 Divide both sides by 8
[tex]\frac{8}{8}c = \frac{56}{8}[/tex]
c = 7

What do you know about Scientific Notation
Answer:
Scientific notation is a way of expressing, and handling, a mathematical expression used to represent a decimal number between 1 and 10 (multiplied by ten), so large numbers can be made with using less digits. An example would be writing 4 x 10³ for 4,000.

solve x-5/y = z for y
Answer:
y=5x−z
Step-by-step explanation:
Step 1: Multiply both sides by y.
xy−5=yz
Step 2: Add -yz to both sides.
xy−5+−yz=yz+−yz
xy−yz−5=0
Step 3: Add 5 to both sides.
xy−yz−5+5=0+5
xy−yz=5
Step 4: Factor out variable y.
y(x−z)=5
Step 5: Divide both sides by x-z.
y(x−z)x−z=5x−z
y=5x−z

Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator
24 min to 64 min
Answer: 3/8
Step-by-step explanation:
24 min to 64 min as a fraction is [tex]\frac{24}{64}[/tex]
Now write the fraction is simplest form by dividing it by their greatest factor.
The GCF of 24 and 64 is 8
24/8 = 3
64 /8 = 8
So the ratio will be 3/8

What is the distance between M(9, −5) and N(−11, 10)?
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{25 \: units}}}}}[/tex]
Step-by-step explanation:
Let M ( 9 , -5 ) be ( x₁ , y₁ ) and N ( - 11 , 10 ) be ( x₂ , y₂ )
Finding the distance between these points

-26 - 4m = -2(2m + 13)
Answer:
Your answer would equal the same on the other side.
-26-4m=-4m-26
if you minus 26 from both sides youll have -4m on both sides also. So it would equal. So you have an Equaled equation if that makes sense.
a pile of sand has a weight of 90 kg the sand is put into a small bag a medium bag and a large bag in the ratio 2:3:7
work out the wight of sand in each bag
Answer:
15 kg, 22.5 kg, 52.5 kg
Step-by-step explanation:
Let the common multiplier of the given ratios be x. Therefore, weights of each bag would be 2x, 3x and 7x
According to the given information:
[tex]2x + 3x + 7x = 90 \\ 12x = 90 \\ x = \frac{90}{12} \\ x = 7.5 \: \\ \implies \\ 2x = 2 \times 7.5 = 15 \: kg \\ 3x = 3 \times 7.5 = 22.5 \: kg \\ 7x = 7 \times 7.5 = 52.5 \: kg[/tex]
Hence the weight of sand in bag would be 15 kg, 22.5 kg and 52.5 kg

Draw Conclusions Suppose that A and C are real numbers and A is not 0. What are the x- and y-intercepts of the equation Ay = C? Explain.
Answer:
Horizontal line which goes through the y -axis at the coordinate ( 0, C/A ).
Step-by-step explanation:
Since A is not 0 then C can not be 0 This is a logical deduction from the given formula Ay = C
The equation of any line is y = ax + b, where a is the incline and b is the intercept between the line and the y- axis.
Ay = C
Divide left and right of the = sign by A and you get:
y = C/A
This is the formula for a horizontal line which goes through the y -axis at the coordinate ( 0, C/A ).
Because it is a horizontal line it has an incline of 0.
So a = 0
y = ax + b
a = 0 and b = C/A
y = 0*x + C/A
y = 0 + C/A
y = C/A
On an actual basketball court, the bench area is 9 meters long. How long should the bench be on the scale drawing?
Step-by-step explanation:
Note: It is not given that, 1 cm represents 2m
The bench area on an actual basketball court is 9 meters long.
We need to find how long should the bench be on the scale drawing. Since 1 cm represents 2m. It means 1 m represents 0.5 cm
9 meters will represent,
[tex]\dfrac{9}{0.5}\ cm\\\\=18\ cm[/tex]
Hence, the bench is 18 cm long.
