(-2v-49)x(5v-100)
Multiply each term in the first parentheses by each term in the second parentheses (foil)
-2vx5v-2vx(-100)-49x5v-49 x (-100)
calculate the product
-10v²-2v x(-100)-49x5v-49 x(-100)
-2vx5v
Multiply the numbers
-10v x v
the same of the other one ok is different how i am doing
-2vx5v
If a term doesn't have an exponent , it is considered that the exponent is 1
-10v^ 1 x v
-10v^1 xv^1
Multiply the terms with the same base by adding their exponents
-10v^1 x v^1
-10v^1+1
to add the numbers using a number line, start from zero
1+1=2
Since 1 is positive, move the point 1 unit to the right
The result is 2
Answer: -10v^2
That's it . Hope it wasn't too hard to understand?

Answer:
x = 3
Step-by-step explanation:
Given :
AE = 3, EB = 4, CE = x, and ED = x +1,
Equating chord AB and CD
AE*EB = CE*ED
3*4 = x*(x+1)
12 = x² + x
x² + x - 12 = 0
x² +4x - 3x - 12 = 0
x(x + 4) - 3(x + 4)
(x + 4) = 0 or (x - 3) = 0
x = - 4 or x = 3
Distance can't be negative :
x = 3
Answer:
I believe the there are 9.
Step-by-step explanation: Here is how I thought about it: you have an x sandwich, y sandwich, and z sandwich; x drink, y drink, and z drink, and a dessert. The possible combos would be xxa, xya, xza, yxa, yya, yza, zxa, zya, zza. Hope this helps!
Here, the given equation is,
x^2+y^2+px+6y-3=0
By copairing it with x^2+y^2+2gx+2fy+c=0, we get,
2g=p or, g=p/2
2f=6 or, f=3
c=-3
now the radius is,
r^2=g^2+f^2-c
or, 4^2=(p/2)^2 +3^2 -(-3)
or, 16= p^2/4 +9+3
or, 16-9-3=p^2/4
or p^2/4=4
or, p^2=4×4
or p^2=4^2
or p=4
therefore the rewuired value of p is 4.
Answer:
42in :)
Step-by-step explanation:
All you have to do is multiply 7x6 because u need to find the area.
but if u wanna find the perimeter u have to add all sides.
area is multiply 2 sides.
