The answers to the expressions  are:

  • (x² + 15x + 65)+(2x - 5)(3x + 8) simplifies to 7x² + 16x + 25. The first blank is (B).

  • (4x + 1)(3x - 4)-(5x² - 10x - 12) simplifies to 7x² – 3x + 8. The second blank is (D).

<h3>What is the expressions about?</h3>

Others are:

  • (8x² + 91x + 4)+(3x +2)(x - 5) simplifies to 11x² + 6x - 6. The second blank is (A).

  • (6x + 1)(3x - 7) - (7x² -34x - 20) simplifies to 11x² - 5x + 13. The second blank is (C).

Note that:

(x²+15x+65)+(2x-5)*(3x+8)

(x²+15x+65)+(6x²+16x-15x-40)

(7x²+16x+25)

Therefore its answer will be  letter B which is (7x²+16x+25)

atroni [7]

Answer: 63.59cm²

Step-by-step explanation:

The area covered by the pitch will be gotten by finding the value of the area of the circle and this will be:

Area of q circle = πr²

where,

π = 3.14

r = radius = diameter/2 = 9cm/2 = 4.5cm

Area = πr² = 3.14 × 4.5²

= 3.14 × 20.25

= 63.59cm²

Therefore, the area covered by the pitch is 63.59cm²

4log x-1/2log y+3log z
babymother [125]
Following rules of logs, we can do the following:

log x^4 - log y^(1/2) + log z^3

Combine the first and 3rd factors to get    log [x^4*z^3]

Seeing that the neg. sign signifies division, write this new term - log y^(1/2) as a quotient:

        [x^4*z^3]
log ----------------
           y^(1/2)

Next time, please include the instructions when you present your problem.
Thx.
