5. Factorise: p2 - 11p +30

Answers

Answer 1
Answer:

Answer:

(p - 5)(p - 6)

Step-by-step explanation:

Given

p² - 11p + 30

Consider the factors of the constant term (+ 30) which sum to give the coefficient of the x- term (- 11)

The factors are - 5 and - 6, since

- 5 × - 6 = + 30 and - 5 - 6 = - 11 , thus

p² - 11p + 30 = (p - 5)(p - 6) ← in factored form
Answer 2
Answer:

Answer:

(p - 5)(p - 6)

Step-by-step explanation:

p^2 - 11p + 30

find what two numbers added together is -11 but multiplies together is 30, its' -5 and -6 so:

(p - 5)(p - 6)

Find the surface area of the prism.A. 1589 ft2
B. 9534 ft2
C. 811,551 ft2
D. 1,623,102 ft2

Answers

Simple...if this is a right rectangular prism..then you already know the formula for surface area...

Surface Area: 2(wl+hl+hw)

plug in what you know...

l=729

w=413

h=447

2((413)(729)+(447)(729)+(447)(413))

Surface Area≈1.62*10^(6)  (≈ symbol means it's approximate)

SA≈1,620,000

Thus, your answer, D.

3/5x -15=6/5x+12This is a problem my grandson had to complete. I do not know how to work it. can you show me step by step how to do it so I can hep him?

Answers

Simplify 35x to 3x5

3x5−15=65x+12

2. Simplify 65x to 6x5
3x5−15=6x5+12

3. Multiply both sides by 5
3x−75=6x+60

4. Subtract 3x from both sides
−75=6x+60−3x

5. Simplify 6x+60−3x to 3x+60
−75=3x+60

6. Subtract 60 from both sides
−75−60=3x

7. Simplify −75−60 to −135
−135=3x

8 .Divide both sides by 3
−1353=x

9. Simplify 1353 to 45
−45=x

10. Switch sides
x=−45
