What is 2(6+7)= 3(5+2)

1 answer:

Komok [63]3 years ago

7 0

Solution:

2(6+7)= 3(5+2)

Step ; 1 { Solving first Term i.e LHS }

LHS : 2 ( 6 + 7)

☞ 2 ( 13)

☞ 2 × 13

☞ 26

Now, RHS ; 3 ( 5 + 2)

☞ 3 ( 7)

☞ 21

From Equation 1 and 2, We can LHS and RHS are not Equal.

Therefore, 26≠ 21.

A model of a building is 18 inches tall. If the building is really 678 feet tall, how tall is a window that is 1/9 in on the mod

ipn [44]

Answer:

50.2in or 4.2ft

Step-by-step explanation:

This is a problem about proportions so I generally set up my problems like below. I just set some variable here to make it easier to refer back to the measurements for each. You don't have to do this, I am just showing it for clarity. I will convert everything to inches too. We need to find the real window height.

Mb = model building = 18in

Mw= model window = $\frac{1}{9}$ in

Rb = real building = 678ft = 8136in

Rw = real window = ?

$\frac{Mw}{Mb}$ = $\frac{Rw}{Rb}$

$\frac{1/9}{18}$ = $\frac{Rw}{8136}$

$\frac{1}{9*18}$ = $\frac{Rw}{8136}$

$\frac{1}{162}$ = $\frac{Rw}{8136}$

$\frac{1*8136}{162}$ = $\frac{8136*Rw}{8136}$

$\frac{8136}{162}$ = Rw

$\frac{452}{9}$ = Rw

Rw ≈ 50.2in ≈ 4.2ft

Find all the zeroes of the equation. x4 – 6x2 – 7x – 6 = 0

NeX [460]

Answer:

-2, 3, -0.5 + 0.866i, -0.5 - 0.866i.

Step-by-step explanation:

As the last term is -6 , +/- 2 , +/- 3 are possible zeroes.

Try 2:-

(2)^4 - 6(2)^2 - 7(2) - 6 = -28 so 2 is not a zero.

3:-

(3)^4 - 6(3)^2 - 7(3) - 6 = 0 so 3 is a zero.

(-2)^4 - 6(-2)^2 - 7(-2) - 6 = 0 so -2 is also a zero.

Divide the function by (x +2)(x - 3), that is x^2 - x - 6

gives x^2 + x + 1

x^2 + x + 1

So we have x^2 + x + 1 = 0

x = [-1 +/- √(1^1 - 4*1*1)] / 2

= -1 + √(-3) / 2 , - 1 - √(-3) / 2.

= -0.5 + 0.866i, -0.5 - 0.866i

Angle math Hw. Pls help

timurjin [86]

Answer:

x = 45°

Step-by-step explanation:

We can tell that "x + 115" and 160° are vertically opposite angles, which means that they are equal. (Refer to image)

⇒ x + 115 = 160

⇒ x = 160 - 115

⇒ x = 45°
