Answer: 7+(2.5)
Step-by-step explanation: n-(-n) = n+n
Hopefully this helps
The "width" of the shape in #19 is 4. The "length" is the average of 6 cm and 10 cm, and is 16 cm/ 2, or 8 cm.
Then the area of this trapezoid is (8 cm)(4 cm) = 32 cm (answer)
Answer:
it should be c = 5f/9 - 160/9 if solving for c.
<u>Answer with step-by-step explanation:</u>
A. WX is perpendicular to XY - TRUE:
(since X is adjacent to X and Y and all angles are 90 degrees in a square, therefore WX is perpendicular to XY)
B. ∠W is congruent to ∠X - TRUE:
(all angles in a square are equal to each other)
C. ∠W is supplementary to ∠X - TRUE:
(∠W and ∠X both are right angles which add up to 180 degrees so they are supplementary angles)
D. WXYZ is a rhombus - TRUE:
(a rhombus has all sides equal in length and so has a square so it is a rhombus)
E. WXYZ is a trapezoid - FALSE:
(a trapezoid has only one pair of parallel sides while a square has two pairs of parallel sides)
F. WX is parallel to YZ - TRUE:
(WX and YZ are parallel to each other)
Equal because these numbers are of the same value
