Monica forgot to multiply by 1/2
The area of the fabric is 243 in.2
Explanation:
The formula for the area of a triangle is:
1/2 • base • height
Monica’s error is that she only multuplied the base and height, without multiplying 1/2 also.
The area of the fabric is 243 in.2 because:
1/2 • 18 • 27 = 243
Or you could just divide the wrong area Monica solved (486 in2) by 2. You will also get 243 in.2
Have a nice day! And mark me brainliest please!
Answer:
x = ± 7
|-7|-2=5
|7|-2=5
± means positive or negative
Step-by-step explanation:
|x|-2=5
Get x by itself by adding 2 to both sides.
x - 2 + 2= 5 + 2
-2 + 2 cancels out
x = 5 + 2
x = 7
Absolute value is how far a number is from 0.
x can be either positive or negative.
You can solve this two ways:
One is by substituting in the numbers until you get 15=15.
6(0)-9=15
0-9=15
-9=15
6(1)-9=15
6-9=15
-3=15
6(2)-9=15
12-9=15
3=15
6(3)-9=15
18-9=15
9=15
6(4)-9=15
24-9=15
15=15
Solution is x=4
or you can find the value of x
by first adding 9 to both sides to get x by itself
6x-9=15
6x=24
Then divide by 6
x=4
You're basically multiplying the number and the variable with the number on the outside of the parenthesis.
So, 8(x + 7). You multiply 8 and the variable to get 8x. The same with '7'.
8 times 7 is 56.
Answers:
A) 8x + 56
B) 66 + 6x
C) 8x + 8
