Answer:
4x+7z
Step-by-step explanation:
4x + 2z + z +4z is the expression
The simplified expression is just the terms combined
so,
4x + 2z+1z+4z
4x+3z+4z
4x+7z
10850 would be I'm favor of building the park and 4650 would not
Do a proportion
30/100= x/30
30 x 30= 900
900 divided by 100= 9
Answer is 9 students
The power will be negative as the number is < 1.
Count the number of digits after the decimal point until you came to first number > 0. (counting this number)
This comes to 5 so the answer is
1 * 10^-5 or just 10^-5
Let the side of one square be x. Area = x*x = x²
Then the side of other square would be 2x , Area = 2x*2x = 4x²
Combined area = x² + 4x² = 5x²
This combined area = 45 cm²
Therefore 5x² = 45 Divide both sides by 5
x² = 45/5
x² = 9 Take square root of both sides
x = √9
x = 3
Length of larger square is 2x = 2*3 = 6 cm
Length of larger square = 6cm
