Since the total is 42 divide by two since they are the same length so it would be 21
Answer:
a translation of (-2,4)
Step-by-step explanation:
Answer:
Please see attached image and all steps below for both parts
Step-by-step explanation:
Task 1
The following system of equations includes a linear equation and a quadratic one:

it can be solved by using substitution in the second equation of the variable "y" by the linear expression of the first equation:

and this product of two factors will e zero when either factor is zero, that is: when x = 0, or when x = 9 [to make zero the binomial(x - 9)]
There are two solutions: x = 0 and x = 9.
When we graph both expressions in the system, we see that the line intercepts the parabola at the points (0, 2) and (9, 11). See attached image.
Task 2
Part 1:
Let's pick 30 as a number larger than 25. 30 can be written as 40 - 10
So we can use:

to calculate its square.
Part 2:
let's choose a=9 and b=10 so we use:

Answer:
circumference is 50.24cm
Step-by-step explanation:
π
= 200.96
r =
=
=8
Circumference = 2πr = 2 x.3.14.x 8 = 50.24
Answer:
The answer is 9 + 21b
Step-by-step explanation:
Simplify the expression.
