Why -4 x (-4) = 16 not -16? Simple...

Mathematics
1 answer:
Illusion [34]3 years ago
4 0
The reason why it is a positive 16 and not a negative 16, is because when you multiply a negative number with another negative number  you will always get a positive number. But, if you multiple a negative number with a positive number, you will get a negative. So, in order for you to get a -16, the equation would have to be -4*4=-16.

Answer:

1) 36

2) 190

3) 72 units

Step-by-step explanation:

1)  2x4 = 8 units area for rectangle

(4-2) x4 /2 = 4 units

6 x 4 = 24 units

8 + 4 + 24 = 36

2) 3 x 10 / 2 = 15 units

   5 x 10 /2 = 25 units

   15 x 10 = 150 units

   150 + 25 + 15 = 190 units

3) 6 x 3 / 2 = 9 units

   6 x 9 = 54 units

   6 x 3 / 2 = 9 units

9 + 9 + 54 = 18 + 54 = 72 units

In the following figure, triangle ABC and triangle DEF are similar. What is the value of x ? Triangle ABC and triangle DEF are s
Shtirlitz [24]
X = 25.5 mm.

Using the similarity statement given, that ΔABC ~ ΔDEF, we set up a proportion:

8.5/x = 4/12

Cross multiply:
4*x = 8.5*12
4x = 102

Divide both sides by 4:
4x/4 = 102/4
x = 25.5

melamori03 [73]

Answer:

a person travel 50 ft from the bottom to the top of the escalator

Step-by-step explanation:

An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle

The escalator forms a right angle triangle

opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse

let x be the hypotenuse

sin(theta)=\frac{opposite}{hypotenuse}

sin(30)=\frac{25}{x}\\x sin(30)= 25\\x=\frac{25}{sin(30)} \\x=50\\

a person travel 50 ft from the bottom to the top of the escalator
