(4pq+3q)² - (4pq - 3q)²
Answer:
48pq².
Step-by-step explanation:
(4pq+3q)² - (4pq - 3q)²
This is the difference of 2 squares so we can use the identity
a^2 - b^2 = (a - b)(a + b):
(4pq+3q)² - (4pq - 3q)²
= (4pq + 3q - (4pq - 3q)(4pq + 3q + (4pq - 3q)
= (4pq + 3q - 4pq + 3q)(4pq + 3q + 4pq - 3q)
= 6q * 8pq
= 48pq².
Answer:
48pq²
Step-by-step explanation:
As we know,
(a + b)² = a² + 2ab + b²
and
(a – b)² = a² – 2ab + b²
So,
(4pq+3q)² - (4pq - 3q)²
= [(4pq)² + 2 X 4pq² X 3q + (3q)²] – [(4pq)² - 2 X 4pq² X 3q + (3q)²]
= (16p²q² + 24pq²+ 9q²) – (16p²q² – 24pq²+ 9q²)
= 16p²q²+ 24pq²+ 9q² – 16p²q²+ 24pq² – 9q²
= 24pq² + 24pq²
= 48pq²
Chris is six years older than his sister Kennedy. The sum of their ages is 38. Write an equation to find Chris and Kennedy's ages. Make certain that you indicate what the variable represents.
Answer:16 , 22
Step-by-step explanation:
Given
Chris is six-year older than his sister
The sum of their ages is 38
Suppose the age of Chris sister is x
So Chris age is [tex]x+6[/tex]
the sum is
[tex]\Rightarrow x+x+6=38\\\Rightarrow 2x+6=38\\\Rightarrow 2x=32\\\Rightarrow x=16[/tex]
Chris age [tex]16+6=22\ \text{years}[/tex]
Chris sister Kennedy's age [tex]16\ \text{years}[/tex]

Write an equation for the sine wave. What is the amplitude and period?
Answer:
Amplitude is the distance between the center line of the function and the top or bottom of the function, and the period is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat. Using this equation: Amplitude =APeriod =2πBHorizontal shift to the left =CVertical shift =D.

What is the product of the complex numbers below?
(3-9i)(6-i)
Answer:
(9-57i)
Step-by-step explanation:
We need to find the product of the given complex number i.e.
(3-9i)(6-i)
It can be solved as follows :
(3-9i)(6-i) = 3(6) +3(-i) +(-9i)(6) + 9i(i)
= 18-3i-54i+9i²
We know that, i² = -1
So,
= 18-3i-54i+9(-1)
= 18-57i-9
= 9-57i
So, the product of the given complex number is (9-57i).

you spin the spinner shown below once. each sector shown has an equal area. what is P(ladybug)
Answer:
1/5 or 20%
All sectors have an equal area, so that means that all have an equal chance of being landed on. There is only 1 sector containing a ladybug out of all 5 sectors. That means you have a 1 out of 5 chances of landing on the ladybug if you spin once.

Answer:
The equation for the speed of the train is: 162 = 3x
I think the speed of the train is 54 miles per hour
Step-by-step explanation:
We know that:
y = distance in miles
x = speed of train (miles/hour)
t = time traveled from the departing station (hours)
The equation: y = xt is given, we can therefore substitute the give values:
y = xt or tx
162 = 3x (This would be the equation)
Now we can find x by diving 3 on both sides of "="
162/3 = x
54 = x (This would be the speed of train)

Two apples cost 60 cents. How much do five cost?
cost?
Answer:
5 apples cost = 150 /-
Step-by-step explanation:
Two apples cost = 60 /-
Then 1 apple cost = 60 ÷ 2
= 30
∴ 1 apple cost = 30 /-
Then 5 apples cost = 30 × 5
= 150
∴ 5 apples cost = 150 /-

correctly describe the slope of the graph of 2x + 5y = 6?
Answer:
[tex]2x + 5y = 6z[/tex]
ok
The slope of the graph of 2x + 5y = 6 is; -2/5.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
The slope of the line y = mx + c is calculated as follows:
m = Δy/Δx
To find the slope of the line of 2x + 5y = 6
Therefore, the slope of the line is;
2x + 5y = 6
5y = 5 - 2x
Now divide by 5
y = 1 - 2/5x
When we simplify it, then we get;
m = -2/5
Hence, the slope of the graph of 2x + 5y = 6 is; -2/5.
