Answer:
9 square units
Step-by-step explanation:
Draw a rectangle around the triangle. The rectangle is 4 units tall by 6 units wide. The area of the triangle equals the area of the rectangle minus the triangles in the corners.
A = (4)(6) − ½(2)(4) − ½(1)(4) − ½(3)(6)
A = 24 − 4 − 2 − 9
A = 9
Answer:1$ cards = 11 cards 3$ cards= 13
Step-by-step explanation:the first equation is -x-y=-24 and the second is x+3y=50. Solving them as a system will get 2y=26 to y=13 then plug in 13 to the y for -x-y=-24 to get 11. Mr jacobs is hard I know lol. Use elimination by subtraction and keep the first equation as x+y=24 and then flip to negative
Answer:
44
Step-by-step explanation:
You need a theorem to solve this problem.
<em>Theorem:</em>
<em>Tangent segments drawn to a circle from a point are congruent.</em>
Look at the point below the circle. The segment from that point to point P (length 4), and the segment from that point to point R are congruent according to the theorem above.
Do the same with the other segments. On the left side, both tangent segments have length 12. On the right side, both tangent segments have length 6.
perimeter = 4 + 4 + 12 + 12 + 6 + 6
perimeter = 44
