Answer:
7x-11
Step-by-step explanation:
the need is to solve iy
The formula of a lateral area of a triangular prism is
LA = (1/2)*(perimeter of a triangle)*h
The perimeter of a triangle is the total of all sides.
Since the length of the base of a triangle is not given yet, use the Pythagorean theorem
base² = 7² + 24<span>²
base</span><span>² = 625
base = 25 cm
The perimeter is 7 + 24 + 25 = 56 cm
Finally the lateral area is
LA = (1/2)*56*30 = 840 cm</span><span>²</span>
Answer:
16: y=4x+14 17: 12 18: when you simplify it all individually you get x=3 for both equations. 19: $6.69
Step-by-step explanation:
16:y-2=4(x+3) distribute 4 and get y-2=4x-12. Add 2 to both sides to get y-4x+14.
17:x+2y=4 and 3x+6y=? divide 3x+6y by three and you get x+2y=4. This means you can just multiply the 4 by 3 to get the answer.
18:3x-5=4 and 3x-3=6. For the first one add 5 to both sides to get 3x=9 then divide both side by 3 to get x=3. For the second one add 3 to both sides to get 3x=9. Again divide both sides by three to get x=3.
19: $18-$4.62=13.38 since he wants 2 models divide 13.38 by 2 to get 6.69.
Simple....
we take two points on this line...in this case..
(2,1) and (4,3)
Using:
Thus, your answer.
Step-by-step explanation:
cact = corresponding angles of congruent triangles.
