Have you tried doing (3x+18)+(9x-27)=99
Answer:
that's the picture,, but what is the question ??
Answer:
27 inches
Step-by-step explanation:
To find the length of the diagonal, we just need to use the cosine relation of the 48° angle.
The adjacent side to the angle is the height of the canvas, and the hypotenuse formed is the diagonal of the canvas. So, we have that:
cos(48) = height / diagonal
0.6691 = 18 / diagonal
diagonal = 18 / 0.6691 = 26.9 inches
Rounding to the nearest inch, the diagonal of the canvas measures 27 inches
Answer:
Here's a possible example:
Step-by-step explanation:

Each piece is linear, so the pieces are continuous by themselves.
We need consider only the point at which the pieces meet (x = 3).

The left-hand limit does not equal ƒ(x), so there is a jump discontinuity at x =3.
