Answer:


Step-by-step explanation:
Let
x ---> the number
we know that
The algebraic expression is equal to multiply the number by 4, add 5 and equal 8
so

Solve for x
subtract 5 both sides

Divide by 4 both sides

Answer:
12^x
Step-by-step explanation:
Absolute. Value. Of. |12^x-8|. Is. 12^x + 8
12^x + 8= 2^3. So. 12^x. +8.=8
12^x+8-8=8-8
12^x=0. Left. With. 12^x?
Answer:
y=3x+4
Step-by-step explanation:
since the line is parallel it has the same slope so we have y = 3x + b. plug in the point (2,10) to get 10 = 3*2 + b, so b=4. so the equation is y = 3x +4
Answer:
4:25
8:125
Step-by-step explanation:
Surface Ratio is the "Similarity Ratio" to the power of 2
Volume Ratio is the "Similarity Ratio" to the power of 3
It's logical and deductable by paying attention to the correlation between the "Side"s(or "Diameter"s) and the "Surface" and the "Volume"s in simple shapes like Circles and square.
By paying attention to the formula of the "Surface Area" and the "Volume" or the m /m^2 /m^3 ( the units of measurement) we can easily notice the relation.
