Answer:
Let
x = number of yards mowed
The domain of the function is
5 ≤ x ≤ 20
If we multiply the inequality by 25, we get
125 ≤ 25*x ≤ 500
Which is the same as
125 ≤ f(x) ≤ 500
(Range of the function)
Domain 5 ≤ x ≤ 20
Range 125 ≤ f(x) ≤ 500
Answer: 243
Third term of g.p. = ar^2 =3
General term = ar^n-1
Product of first five terms
= a^5 x r^0+1+2+3+4
= a^5 x r^10
= (ar^2)^5
=(3)^5
= 243
Answer
364 i think
Step-by-step explanation:
find the area of triangles + area of rectangles
area of triangles: b x h x 1/2
6 x 4 x 1/2
= 12
but two triangles, so . double it and then you get 24 for the two triangles areA
area of rectangles;
l x w
22 x 6
= 132
but two up and down rectangles, so double it = 264
now back rectangle:
l x w
22 x 4
= 88
Add it all up together and you have the surface area!
Surface Area - The area of the surface of the 3D object, NOT volume
pls mark brainliest unless someone else answered it or im wrong thank you! :D
Answer:
Step-by-step explanation:
3x²+3x-6
=3(x²+x-2)
=3(x²+2x-x-2)
=3[x(x+2)-1(x+2)]
=3(x+2)(x-1)
Answer:
13, 15
Step-by-step explanation:
Let x represent the smaller of the two integers. Then the larger is x+2. The required relation is ...
x² = 154 +(x +2) . . . . . . the smaller squared is 154 more than the larger
x² -x = 156 . . . . . . . . . . subtract x
x² -x +1/4 = 156.25 . . . complete the square
(x -1/2) = √156.25 = 12.5 . . . . take the square root
x = 13 . . . . . add 1/2
The two integers are 13 and 15.

13² -15 = 169 -15 = 154 . . . as required
