Answer:
2x^2
Step-by-step explanation:
if you draw a diagonal, you will have two triangles with base x and height x
so area= 2 * 1/2 * b * h = b * h= 2x * x
A) is ok; its slope is the neg. reciprocal of the given slope 4, as is required for
perpendicular lines.
B) not feasible; its slope is +1/4, not the negative reciprocal of 4 (-1/4).
C) OK
D) OK (slope is -1/4)
56 is 80% of 70.
70 x 0.80 = 56
To find the base number, divide 56 by 0.80:
56 / .8 = 56 / (8/10) = 56 x (10/8) = 560/8 = 70
Breads/cereals;
11 * 140 = 1540 calories
Fruits/vegetables;
9 * 60 = 540 calories
Meat/milk;
x * 180 = 2800 - (1540 + 540)
180x = 2800 - 2080
180x = 720
x = 4 servings
