Answer:21
Step-by-step explanation:
It's a 1-7 proposition for every ft on the smaller triangle it is 7ft on the big one
Answer:
8x
Step-by-step explanation:
d - 2 < -1 is how this inequality would be displayed.
However, we can solve for the value of d by treating this like a standard algebraic equation.
d - 2 < -1
<em><u>Add 2 to both sides.</u></em>
d < 1
The value of d is less than 1.
Let me know if you have any other questions.
To begin, if the base is a square, then each side of this square would be 3 ft. there are 4 traingles, and the area of a triangle is 1/2bh, the height being the slant height and the base being one side of the square. Therefore, the surface area is 4(1/2)(3)(8)+9=57 ft^2
