Answer: you only add 4 each time
Step-by-step explanation:
Answer:82cm^2
Step-by-step explanation:
Area of shape=area of big rectangle + area of small rectangle
Length of big rectangle=10
Width of big rectangle=7
area=length x width
area of big rectangle=10x7
area of big rectangle=70
Length of small rectangle=4
Width of small rectangle=10-7=3
Area=length x width
area of small rectangle=4x3
area of small rectangle=12
Area of shape=70+12
Area of shape=82cm^2
Answer:
x = 6 and -6
Step-by-step explanation:
x²-36 = 0
isolating x
x²-36+36 = 0+36
x²=36
√x² = √36
x = ±6
Answer:
46

<u>The points given:</u>
- (−6, −2), (0, −10), (5, 2), (−1, 10)
They form a rectangle as seen in the picture.
We can notice that this is a parallelogram, as respective lines have same difference of coordinates.
<u>So calculating only the two of the sides will be sufficient to get its perimeter:</u>
- a = √(-1+6)² + (10+2)² = √25+144 = √169= 13
- b = √(0+6)² + (-10+2)² = √36+64 = √100 = 10
<u>So, the perimeter:</u>
