Answer:

Step-by-step explanation:

x^(a-(-b))(a-b).x^(b-(-c))(b-c).x^(c-(+a))(c-a)

x^(a+b)(a-b).x^(b+c)(b-c).x^(c+a)(c-a)

x^(a2-b2).x^(b2-c2).x^(c2-a2)

x^a2-b2+b2-c3+c2-a2

x^0

Find the area and perimeter. The area is ... and the perimeter is ...

Anarel [89]

Answer:

Area: $17a^2b$

Perimeter: $P = 10a^2+10b$

Step-by-step explanation:

Area

The area of the entire rectangle that is 4b by $a^2+3a^2+a^2 = 5a^2$ is found using A = l*w. If w=4b and l= $5a^2$ then the area is:

$A=l*w\\A=5a^2(4b)\\A=20a^2b$

However there is a cutout in the middle. Find the area of the cut out and subtract from the total area.

The cutout is $3a^2$ by b. So the area is:

$A=l*w\\A=3a^2*b\\A=3a^2b$

Subtract $20a^2b - 3a^2b = 17a^2b$

Perimeter

The perimeter is the distance around the entire figure. To find it, add each side length. Then add like terms together.

$P = a^2 +b + 3a^2 + b +a^2+4b+5a^2+4b\\P = 10a^2+10b$

a 12 pound cat is prescribed amoxicillin at 5 mg kg twice a day for 7 Days the oral medication has a concentration of 50 mg ml a

velikii [3]

The first step in determining the answer will need to be to convert the weight from imperial to metric. 12lbs ~ 5.44311kg Then we need to look at the total amount of amoxicillin needed. At 5mg/kg is ~27.5mg twice per day. The concentration is 50mg per ml. Knowing that the cat needs around 55mg, that leads us to 1.1ml daily.

Choose the abbreviation of the postulate or theorem that supports the conclusion that WAS NOT. Given: WS = NT, AS = OT, S = T.

koban [17]

Answer: The abbreviation that supports the conclusion is SAS

Step-by-step explanation:

Given WS=NT

AS=OT

S=T

We have two triangles named WAS and NOT

where we have two sides (WS=NT and AS=OT)

and an angle(S=T) equal

Since the angle is between the two sides

So the postulate that supports is SAS

i.e Side Angle Side

the distance that a spring will stretch varies directly as the force applied to the spring. A force of 12 pounds is needed to st

vodka [1.7K]

Answer:

Force required, F = 20 pounds

Step-by-step explanation:

We have given,

force needed to stretch a spring , F = 12 pounds

Stretched length, x = 9 inches

Since, spring force formula can be given as: F = kx

i.e 12 = k · 9

or k = $\frac{12}{9}$ = 4/3

Now we need to find force for the stretch length = 15 inches

i.e F = kx , here x =15inches , k = 4/3 and F= ?

or F = (4/3) · 15

or F = 20 pounds

Hence force required, F= 20 pounds
