Answer:

704π m^2

Step-by-step explanation:

Given data

radius r= 16m

Slant height l= 28m

Required

The surface area of the cone

The expression for the surface area is given as

T.S.A=πrl+πr^2  

substitute

T.S.A=π*16*28+π*16^2

T.S.A=448π+256π

T.S.A=704π m^2

Hence the T.S.A is 704π m^2

Find the following algebra, I am in class and plz give explanation
Lelechka [254]

1) Solving 4a+4b-ac-bc we get (a+b)(4-c)

2) Solving 16a^4-8b we get 8(2a^4-b)

3) Solving x^2-8x+15 we get (x-3)(x-5)

Step-by-step explanation:

We need to solve the following expressions:

1) 4a+4b-ac-bc

We will solve this expression by factoring common terms:

4a+4b-ac-bc

Factoring 4 from 4a+4b and -c from -ac-bc

4(a+b)-c(a+b)

Taking common term

(a+b)(4-c)

2) 16a^4-8b

We will solve this expression by factoring common terms:

16a^4-8b

Taking 8 as common term:

8(2a^4-b)

3) x^2-8x+15

We can solve the expression by breaking the middle term into 2

x^2-3x-5x+15\\Finding\,\,common:\\=x(x-3)-5(x-3)\\=(x-3)(x-5)

Take a factor out of the square root:
Nat2105 [25]

Answer:

See below.

Step-by-step explanation:

Lets take √72:

Factoring 72 to find perfect squares:

72 = 2*2*2*3*3

The largest perfect square in the above = 2*2*3*3 = 36.

So we can write 72 as 36*2.

√72 = √(36 * 2)

√36 * √2

= 6√2.

One more example:

√18  = √(2*3*3)

= √9*√2

= 3√2.

I NEED YALL’S HELP <br> 2x+12=64<br> Step by step
OverLord2011 [107]

Answer:

2x + 12 = 64

x = 26 (mark brain if this helps and is correct)

Step-by-step explanation:

to solve equations with one missing variable we must use the order of operations of equality

step 1: use the subtraction property of equality meaning subtract each side of the equation

ex: 2x + 12 - 12 = 64 - 12   (2x = 52)

step 2: use the division property of equality meaning divide each side of the equation by 2

ex: 2x/2 = 52/2   (x = 26)

step 3: check your answer by putting 26 as x because that is our answer

2(26) + 12 = 64 (multiply 2 * 26)

52 + 12 = 64 (add 52 + 12)

64 = 64 (if both sides of the equation are the same number like 64 = 64 then your answer is true meaning that x is equal to 26)
