Answer:
Answer is 3
Step-by-step explanation:
Because the Perimeter is true and area is true.
Answer:
<h2>204 units²</h2>
Step-by-step explanation:
It's a rectangle. Therefore the opposite sides are congruent.
We have the equation:
2x + 4 = 12 <em>subtract 4 from both sides</em>
2x = 8 <em>divide both sides by 2</em>
x = 4
Put the value of x to the expression 4x + 1:
4(4) + 1 = 16 + 1 = 17
Therefore we have the rectangle with dimesions 17 × 12.
The area of the rectangle:
A = (17)(12) = 204
Answer:
a) 22:53
b)213 min
Step-by-step explanation:
c) 10 17 + 4 = 14 17
she has 2 minutes to spare
Answer:
She incorrectly multiplied 15 X 1/4
Step-by-step explanation:
4πrsquare= 2πrsquare+2πrh
2πrsquare=2πrh
R=h
So h=16/2=8mm
