Answer:

(x + y)(a + 9)

Step-by-step explanation:

Here, we want to factorize the polynomial

We can do this by taking together like terms

Thus. we have that;

9x + ax + ay + 9y

= x(a + 9) + y(a + 9)

= (x+y)(a+ 9)

Answer:

The most simple method for solving systems of equations is to transform one of the equations so it allows for the canceling out of a variable. In this case, we can multiply \displaystyle 3x + y = 8 by to get . Then, we can add \displaystyle 2x + 4y = 12 to this equation to yield , so .

I need this question answered plz help.

wel

Answer:

a.12/13

Step-by-step explanation:

FORMULA: sine of an angle in a triangle is given by, $\frac{opposite side's length}{length of the hypotenuse}$

here, in the given triangle PQR, for angle 'p'

opposite side= QR

adjacent side= PQ

hypotenuse=PR

Therefore, sine of angle p= $\frac{QR length}{PR length} = \frac{12}{13}$

Thus, by using the above given formula, the sine of angle p in the triangle PQR is 12/13.

hence, the trigonometric formulas as mentioned above should be remembered for sure to solve these type of problems

an ice fisherman wishes to cut a hole in the ice which has a diameter of 30 cm. How far around must he cut to create this hole?

olga55 [171]

Given:

Diameter of the hole = 30 cm

To find:

The area of the hole.

Solution:

The radius of a circle is always half of the diameter. It is given that the diameter of the hole is 30 cm. So, the radius of the hole is:

$r=\dfrac{30}{2}$

$r=15$

Area of a circle is:

$A=\pi r^2$

Putting $\pi = 3.14$ and $r=15$ in the above formula, we get

$A=(3.14)(15)^2$

$A=(3.14)(225)$

$A=706.5$

Therefore, the area of the hold is 706.5 square cm.
