Here’s what you can do to make this very simple. Consider that the “missing” space between the rectangles isn’t there. Then, find the area:
10 x 9 = 90 mm
Now, find the area of the “missing” part.
5 x 2 = 10 mm
Finally, you deduct the missing part from the complete rectangle!
90 - 10 = 80 mm
The area of this whole thing is 80 mm!
Answer:
1
Step-by-step explanation:
Any number put to the 0 power is equal to 1.
Does that help?
Answer:
x= 15
y= -3
Step-by-step explanation:
To find the two numbers, write a system of equations with x as one number and y as another:
x+y=12
x-y=18
Use elimination to solve by adding the equations together.
x+y=12
x-y=18
-----------
2x=30
x=15
Substitute x=15 into one equation to find y.
15+y=12
y=12-15
y=-3
Answer:
x = 6
Step-by-step explanation:
EG = 59
EF = 8x - 14
FG = 4x + 1
to find the value of x
EF + FG = EG (same line)
8x - 14 + 4x + 1 = 59
12x -13 = 59
12x = 59 + 13
12x = 72
x = 72 ÷ 12
x = 6
You can even cross check for correct answer
EF + FG = EG
instead of x place the x's value we got
8x - 14 + 4x + 1 = 59
8 (6) - 14 + 4 (6) + 1 = 59
48 - 14 + 24 + 1 = 59
34 + 25 = 59
59 = 59
