Answer:

x = -1

Step-by-step explanation:

-2(x - 5) = 12

-2x + 10 = 12 (this is the mistake, -2 times -5 = + 10)

-2x = 12 - 10

-2x = 2

x = 2/(-2)

x = -1

Answer:

-2(x - 5) = 12

-2x + 10 = 12

-2x + 10 - 10 = 12 - 10

-2x = 2

-2x/-2 = 2/(-2)

x = -1

Thus, The answer is (-1) and the mistake is multiplication of sign i.e.,

[ (-) × (-) = (-) ] this is wrong ×

But

[ (-) × (-) = (+) ] this is right ✓

Answer:

Length of rectangle = 16 cm

Width of rectangle = 4 cm

Step-by-step explanation:

Given:

Area of rectangle = 64 cm²

Find:

Length and width

Computation:

Assume;

Length of rectangle = a

So,

Width of rectangle = a -12

Area of rectangle = l x b

So,

a(a-12) = 64

a² - 12a - 64 = 0

a² - (16-4)a - 64 = 0

a² - 16a+ 4a - 64 = 0

a (a-16) + 4(a-16)= 0

(a-16)(a+4) = 0

a= 16 , a = -4

So,

Length of rectangle = 16 cm

Width of rectangle = a -12

Width of rectangle = 16 -12

Width of rectangle = 4 cm

Kite FGHK is shown. <br> What is the value of m?
Georgia [21]

For this case, the first thing to do is to observe that the figure is symmetrical with respect to the FH axis.

Therefore, the following lengths are the same:

GH = HK

So, by equalizing both sides we have:

5m + 1 = 3m + 7

From here, we clear the value of m.

We have then:

5m - 3m = 7 - 1\\2m = 6

m = \frac{6}{2}\\m = 3

Answer:

The value of m is given by:

m = 3
