Answer:

x² + 12x + 35

Step-by-step explanation:

The area of the blue section is x * x = x².

Pink: x * 7 = 7x

Green: x * 5 = 5x

Orange: 7 * 5 = 35

When we add these up we get x² + 12x + 35. Hope this helps!

Evaluate b2c-1 for b = 8 and c = -4. A.16 B.-16 C.256 D.1/16
netineya [11]

Answer:

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Step-by-step explanation:

How do you break apart the factor 42 using place value?
worty [1.4K]

Hey there!☺

Let's break apart 42.

The 4 is in the tens. The 2 is in the ones.

                            Place Value starting from Thousands

                             Thousands  Hundreds  Tens  Ones

                             _________ ________ ____ _____

                                                                        4          2

So this is how we break up numbers using place value.

Hope this helps!
