Find: (4x²y3 + 2xy2 - 2y) - (-7x?y3 + 6xy2 – 2y)

yKpoI14uk [10]

Answer:

The coefficients are

11,-4 and 0.

Step-by-step explanation:

We are given two algebraic expressions. We are subtracting the second from the first.

First one is:

(4x²y3 + 2xy2 - 2y)

Second expression is:

(-7x?y3 + 6xy2 – 2y)

The given expression:

(4x²y3 + 2xy2 - 2y) - (-7x?y3 + 6xy2 – 2y)

The coefficients are

11,-4 and 0.

This is for literal equations <br> A=4 πr2 (r2)<br><br> i think you solve for r2

Sedaia [141]

Answer:

$r^2=\dfrac{A}{4\pi}$

Step-by-step explanation:

The given equation is A=4 πr².

We need to solve the above equation for r².

We have,

A=4πr²

Dividing both sides by 4π, we get :

$\dfrac{A}{4\pi}=\dfrac{4\pi r^2}{4\pi}\\\\r^2=\dfrac{A}{4\pi}$

Hence, the value of r² is equal to $\dfrac{A}{4\pi}$ .

On each of 3 days, Derrick rode 6.45 km to school, 150 meters to the library, and then 500 meters back home. how many kilometers

Svetradugi [14.3K]

Answer: 21.3 km

Step-by-step explanation:

Given: On each of 3 days the distance traveled by Derrick to school = 6.45 km

The distance rode by Derrick to library = 150 meters

Since, 1 m= $\frac{1}{1000}\ km$

Thus, the distance rode by Derrick to library = $150\times\frac{1}{1000}\ km=0.15\ km$

The distance rode by Derrick to home = 500 meters.

Thus, the distance rode by Derrick to home = $500\times\frac{1}{1000}\ km=0.5\ km$

Distance he rode in each day = $6.45+0.15+0.5=7.1\ km$

Now, Distance he rode in 3 days = $3\times7.1=21.3\ km$
