Answer:
C
Step-by-step explanation:
They both have x as their common like term
using the formula above for finding area of trapezoids
a= 20in.
b=29.2in.
h= height= 12.5in.
(a+b)=20+29.2=49.2in.
(a+b)h= (49.2)12.5= 49.2×12.5=615in.
1/2(a+b)h= 1/2 × 615 in.= 615/2= 307.5in.
therefore the area of the trapezoid is 307.5in.
Three consecutive odd integers would be x, x+2, and x+4 assuming x is an odd integer. The smallest of these is x. Two times x is 2x. The greatest integer is x+4. Three times this is 3 (x+4), and if you distribute you get 3x+12. If 2x exceeds this by 15, you would make it 3x+12-15. If you add the like terms, 12+(-15) is -3. So, you have 2x=3x-3. Subtract 3x from both sides. 2x-3x is -1x, or -x. Now we have -x=-3. Divide by -, or -1 on both sides. Now we have x=3. You can substitute x for 3 for any of the consecutive odd integers to find their value.
Answer:
Right triangle
Step-by-step explanation:
One of the angles of the triangle is equal to 90 degrees. A 90 degree angle is a right angle. That makes it a right triangle.
