First find the area of the triangle: (4 x 6) ÷ 2 = 12
Then the area of the rectangle: 6 x 8 = 48
Last combine: 48 + 12 = 60
Lol, sorry~
Hope this helped tho
Answer:
14
f(x) = 7
-7^2 + 9(7)= -49 + 63 = 14
The perimeter of the printed part of the page is 29 inches.
<u><em>Explanation</em></u>
Length of the sheet of paper is 11 inches and width is or inches.
Width of the margin is or inches.
As the margin is on all sides of the paper, that means both across the length and width of the paper we need to leave inches for that margin.
So, the length of the printed part inches
and the width of the printed part inches.
Thus the perimeter of the printed part of the page will be: inches.
A) angle A = 180-135= 45 degrees
Angles A and 135 are supplementary angles
b) angle B= 135 degrees
because the two 135 angles are vertical angles ( opposite angles made by two intersecting line)
c) angle C = 45 degrees
because angles C and angles A are corresponding angles since line (1) and line (2) are parallel
