x=16cm
y=17cm
Step-by-step explanation:
area of the sheet = 4y
area of the hole = 3x
4y-3x=20
y=x+1, so let's substitute and solve for x
4(x+1)-3x=20
4x+4-3x=20
x+4=20
x=20-4
x=16
y=17
note: my keyboard is starting to act weird and I left out the units (cm) in the explanation to simplify things
Answer:
2.5 cm is the radius
Step-by-step explanation:
The polynomial with a GCF of 5z is 5z * (x + 1) and the equivalent form is 5xz + 5z and 5xz + 4z + z
<h3>How to create the polynomial?</h3>
From the question, we have the GCF of the polynomial to be:
GCF = 5z
So, we represent the polynomial as follows:
Polynomial = GCF * Other factor
Substitute the known values in the above equation
Polynomial = 5z * Other factor
Let the other factor be x + 1
So, we have:
Polynomial = 5z * (x + 1)
Expand the polynomial
Polynomial = 5xz + 5z
Hence, the polynomial with a GCF of 5z is 5z * (x + 1) and the equivalent form is 5xz + 5z and 5xz + 4z + z

A
Step-by-step explanation:
Answer:
Step 3
Step-by-step explanation:
Ernesto was doing well until he got to Step 3.
Its a little mistake but that chabges up the entire problem.
Let me explain-
In Step 2: 3(y+7)-2y is showing that you must distribute the 3 to the y and the 7 however Ernesto only did that for the y.
That would be the answer, hopw this helps.
