Zoe to Hannah is 3 to 7.
We want to know x.
24 to x
three goes into 24 eight times so multiply 7 by eight
x=56
For this case, the first thing you should do is define a variable.
We have then:
g: unknown number.
We now write the expression in algebraic form.
the sum of 5 and a number:
g + 5
Answer:
An expression that means the sum of 5 and a number is:
C. g + 5
The formula of a circle is A = pi * r^2
The diameter is 16cm, half of a diameter is the radius.
16/2 = 8
The radius is 8cm
pi (8)^2 or 3.14 (8)^2 = 200.96
Closest answer will be 201 (option C)
X^2 -8x = 9 is the rewritten version
I used completing the square to solve it and the work it attached below
