8 Tatami mats are needed to cover the floor.
Excercise 1:
No, this is not simplified fully. The full answer would be <span>−7dk+14d−21k</span>−7, not <span>14d - 9 - 21k - 7dk + 2. So, it is not equivalent.
</span><span>
Excercise 4:
</span><span>7dk (2 - 3 - 1) - 7
</span>
Just multiply 7dk into (2) (-3) and (-1)
you'd get:
<span><span>−<span>14dk</span></span>+</span>−<span>7 after simplifying it fully.
</span>
p = parameter
w = width
w+2.75
p = 2w+2(w+2.75) = <span>4w</span>+<span>5.5 = 30
Answer to the last one:
w = 6.125</span>
Answer:
2754
Step-by-step explanation:
Given,
Length = 18 yards is equivalent to 54 feet
Width = 51 feet
So area of the field = Length * width
= 54 x 51
=2754 square feet
(x - 8)² = 144
Take square root of both sides
(x - 8) = √144
x - 8 = 12
x = 12 + 8
x = 20
Original lawn is = 20 feet * 20 feet square
Answer:
he would be at 16.50ft. below sea level.
Step-by-step explanation:
If you are below sea level, the feet would be negative. -11.75 + -4.75 would be -16.50ft below sea level.
Let me know if this helps!!!!
