Hey there! Let us break this down step by step.

According to your information, we have x = 9, and only adding four.

All you have to do, is input your information, getting rid of the X!

Being: 9^2 + 4.

Now, the two right there is called an exponent, all you have to do is multiply the number you have in front of it- in this case it's 9 - by itself.

In this case, it'll be 9 times 9 (9x9), which is 81. After that, you are to add the 4, making your answer.....

Hope this helped!

Even numbers on die: 2,4,6
odd numbers on die: 1,3,5

James measured a piece of construction paper to be 6 3/4 inches wide and 9 2/3 inches long. What is the area of the piece of con

ivolga24 [154]

Answer:

The area of the piece of construction paper is $\frac{261}{4} inches^2$

Step-by-step explanation:

Length of construction paper = $6 \frac{3}{4} inches$

= $\frac{27}{4} inches$

Width of construction paper = $9 \frac{2}{3} inches$

= $\frac{29}{3} inches$

Area of construction paper = $Length \times Width$

Area of construction paper = $\frac{27}{4} \times \frac{29}{3}$

= $\frac{261}{4} inches^2$

Hence the area of the piece of construction paper is $\frac{261}{4} inches^2$

Lane is 10 times Mel's age. If the difference in their age is 27, how old is Mel?

postnew [5]

L - Lane's age
m- Mel's age.
Lane is 10 times Mel's age, so 10m = l
difference in their age is 27 so l - m = 27
Substitute l = 10m and you'll have:
10m - m = 27
9m = 27 /:9
m=3
And l = 10m = 10*3 = 30

So Lane has 3 years old and Mel has 30 years old.
