Answer:
x = 22.
Step-by-step explanation:
6x ≡ 7(mod 25)
6x ≡ 25n + 7 where x and n are integers.
Checking multiples of 25:
25: (n= 1) 25+7 = 32. 6*5 = 2 (mod 25) . Does not fit.
50, 75 , 100 do not fit either.
The answer is 22 because 6*22 = 132 = 125 + 7 = 7(mod 25).

Answer:
390cm³
Step-by-step explanation:
IF you look at the figure attached, you will see that your figure is made up of 3 rectangular prisms.
All you need to do is solve for the volume of each prism and add them up together.
The formula to use to get the volume of a rectangular prism is:
Where:
V = Volume
w = width
l = length
h = height
Let's get the first one and double it because you have rectangular prisms with the same dimensions:
Next we get the rectangular prism in the middle:
Notice that the height of the side rectangular prisms is 12 cm. To get the height of the middle figure, just subtract 5cm and 2 cm from the height because they are the excess of the middle.
12cm - (5cm + 2cm)
12 cm - 7cm = 5cm
Then we plug it into the formula
Now that we have the volumes of all figures, just add them up together:
150cm³ + 240cm³ = 390cm³
