Answer:
[tex]18x^3y[/tex]
Step-by-step explanation:
The area of a trapezium is [tex]\frac{a+b}{2}h[/tex] (where [tex]a,b[/tex] are the parallel sides and [tex]h[/tex] is the perpendicular height)
Area of trapezoid [tex]= \frac{4xy+8xy}{2}3x^2[/tex]
[tex]=6xy(3x^2)[/tex]
[tex]=18x^3y[/tex]
∴ The area of the trapezoid is [tex]18x^3y[/tex]
Hope this helps :)

The track members were required to complete 40 pushups in 5 minutes. Write the rate in 3 different ways.
Answer:
a. 0.133 pushups/s b. 8 pushups/s c. 1200 pushups/s
Step-by-step explanation:
To write the rate in 3 different ways, we have to use seconds, minutes and hours respectively for the time.
So, a. Number of pushups per second
rate, R₁ = number of pushups per second
= number of pushups/ total time in seconds
= 40 pushups/(5 × 60) s
= 40 pushups/300 s
= 0.133 pushups/s
b. Number of pushups per minute
rate, R₂ = number of pushups per minute
= number of pushups/ total time in minutes
= 40 pushups/5 min
= 8 pushups/s
c. Number of pushups per hour
rate, R₃ = number of pushups per hour
= number of pushups/ total time in seconds
= 40 pushups/(5 ÷ 60) s
= 40 pushups/(1/30) h
= 40 × 30 pushups/s
= 1200 pushups/s

Circumference: C = 2πrSurface Area of a Cylinder: SA = 4πr²Step-by-step explanation:
Step 1: Define
C = 21 cm
Step 2: Find Radius r
Substitute [C]: 21 = 2πrIsolate r: 21/(2π) = rRewrite: r = 21/(2π)Evaluate: r = 3.34225 cmRound: r ≈ 3 cmStep 3: Find Surface Area
Substitute [SAS]: SA = 4π(3.34225 cm)²Exponents: SA = 4π(11.1707 cm²)Multiply: SA = 44.6826π cm²Multiply: SA = 140.375 cm²Round: SA ≈ 140 cm²What is the slope of the line?
Answer:
it may be steep slop if it is social study
Hello!
[tex]\large\boxed{m = \frac{3}{2}}[/tex]
[tex]\large\boxed{\text{Slope = \frac{3}{2}}}[/tex]
Use given points and plug them into the slope formula to find the slope of the line:
[tex]\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }[/tex]
We can use the points (2, -1) and (0, -4) to solve:
[tex]\text{Slope } = \frac{ -1 - (-4) } { 2 - 0 }\\\\= \frac{3}{2}[/tex]
Therefore, the slope, or "m" value of the line is 3 / 2.
Six less than 4 times a number is -15 (How to write in equation form?)
Answer:
4x - 6 = -15
Step-by-step explanation:
six less basically means minus 6
something times a number is usually the number given then n (or i usually just like to use x) so in this case 4n or 4x
'is' basically means equal to
put it all together and you get 4x - 6 = -15
sorry is this is confusing
i hope this helps <3

The product (2 + bi)(3 + 2i) is equal to 13i. What is the value of b?
Step-by-step explanation:
Lets FOIL it out:
6+4i+3bi+2bi²=13i
6-4i-13i+3bi+2bi²=0
6-9i+3bi+2bi²=0,but i²=-1
3bi-2b=9i-6
b(3i-2)=9i-6
Divide both sides by (3i-2)
b=(9i-6)/(3i-2)
Rationalize the expression by multiplying through by the conjugate of (3i-2) which is (3i+2)
b=(27i²+18i-18i-12)/(9i²+6i-6i-4),again i²=-1
b=27i²-12/9i²-4
b=-27-12/-9-4
b=-39/-13
b=3

Given the functions below, find the products identified.
f(x) = 7x - 9
g(x) = -2x + 1
h(x) = 3x + 5
j(x) = -x - 11
What is the product of f(x) and g(x)?
Answer:
f(x) * g(x) =(7x-9)(2x+1)
=14x^2+7x-18x-9
=14x^2-11x-9

value of x?
a 8.5
b. 31.5
c. 13.5
d. Cannot be determined
Answer:
Step-by-step explanation:
if the angles form a linear pair, that means their sum=180
10x-63+8x=180
18x=180+63
x=243/18=13.5 choice c
