Answer:

182 m²

Step-by-step explanation:

The formula for surface area of a rectangular prism is;

Surface Area = 2(wl) + 2(lh) + 2(hw) where w is the width, l is the length and h is the height.

SA = 2(2 * 17)m² + 2(17 * 3)m² + 2(3 * 2)m²

= 2(34)m² + 2(51)m² + 2(6)m²

= 68 m² + 102 m² + 12 m²

= 182 m²

8x^2+5=22x Need help learning factoring please put work so I can understand

sp2606 [1]

Answer: (2x - 5) • (4x - 1)

STEP 1 : Equation at the end of step 1

(23x2 - 22x) + 5

STEP 2 : Trying to factor by splitting the middle term

2.1 Factoring 8x2-22x+5

The first term is, 8x2 its coefficient is 8 .

The middle term is, -22x its coefficient is -22 .

The last term, "the constant", is +5

Step-1 : Multiply the coefficient of the first term by the constant 8 • 5 = 40

Step-2 : Find two factors of 40 whose sum equals the coefficient of the middle term, which is -22 .

-40 + -1 = -41

-20 + -2 = -22 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -20 and -2

8x2 - 20x - 2x - 5

Step-4 : Add up the first 2 terms, pulling out like factors :

4x • (2x-5)

Add up the last 2 terms, pulling out common factors :

1 • (2x-5)

Step-5 : Add up the four terms of step 4 :

(4x-1) • (2x-5)

Which is the desired factorization

Final result : (2x - 5) • (4x - 1)

Suppose f'(7)=9 and g(7)= 5. <br> Find h'(7) where h(x) = 3f(x) + 2g(x) + 7<br><br> h'(7)=???

Ratling [72]

Answer:

The value of h'(7) = 44 .

Step-by-step explanation:

Given:

f'(7)=9 and g(7)= 5

We have to find : h'(7)

Also,

⇔ $h(x) = 3f(x) + 2g(x) + 7$ ...equation (i)

Plugging the value of 'x' = 7 in equation (i) the equation can be re-framed as:

⇔ $h(7) = 3f(7) + 2g(7) + 7$

Now plugging the value of f'=(7)=9 and g(7)=5 in the above equation:

⇔ $h(7) = 3(9) + 2(5) + 7$

⇔ $h(7)=27+10+7$

⇔ $h(7)=44$

So the value of h=(7) = 44 .

Eric is adding water to a 60

Archy [21]

Answer:

After 2.5 minutes the pool will have 27 gallons of water.

Step-by-step explanation:

The pool has already 12 gallons of water and Eric wants to fill it to at least 27 gallons.

The water is flowing at a rate of 6 gallons per minute.

Let, after t minutes the pool will have at least 27 gallons of water.

Therefore, we can write the equation as

27 = 12 + 6t

⇒ 6t = 15

⇒ t = 2.5 minutes.

Therefore, after 2.5 minutes the pool will have 27 gallons of water. (Answer)
