Step-by-step explanation:
9x+79+56=180(sum of angles of triangle)
9x+135=180
9x=180-135
x=45÷9
x=5
Answer:
Step-by-step explanation:
It's essential that you use the symbol " ^ " to indicate exponentiation.
Expanding f(x) = (x + 14)^2 results in x^2 + 28x + 196 (which is in standard form)
Break the shape into smaller rectangles and solve for there areas. Then add the areas together to get the total area of the figure. See the picture below where I solved the problem
Answer:
The correct option is 1 and 4 are correct.
Step-by-step explanation:
The dilation is the enlargement and comparison of a figure according to the scale factor from the given center of dilation.
The rule DO,2(x,y)(2x,2y) express the dilation with factor 2 and the center of dilation is origin. It shows the enlargement of the triangle. The sides of image is twice of the preimage.
In dilation the corresponding angles remains same and the corresponding sides are equal.






Therefore option 1 and 4 are correct.
