Answer:
1) a right triangle
Step-by-step explanation:
One of the caractheristics of a right triangle, the one in which the sum of the two sides squared is the hypotenuse squared(Pytagorean Theorem), is also the the altitudes of a triangle meet at one of the triangle’s vertices. So 1) is the answer to this question.
6xy+32
You multiply 8x by each number and get
24/4xy+32 You can simplify the 24/4 to get six. so your answer is
6xy+32
Answer:
length x and width x-2
perimeter of rectangle=2[l+b]=2[(x-2)+x]=4x-4 is your answer
Answer:
x*15% (x times fifteen percent)
Step-by-step explanation:
Say x is 20, you multiply 20 times 15% and that will be your answer
Answer:
The area of one trapezoidal face of the figure is 2 square inches
Step-by-step explanation:
<u><em>The complete question is</em></u>
The point of a square pyramid is cut off, making each lateral face of the pyramid a trapezoid with the dimensions shown. What is the area of one trapezoidal face of the figure?
we know that
The area of a trapezoid is given by the formula

where
b_1 and b-2 are the parallel sides
h is the height of the trapezoid (perpendicular distance between the parallel sides)
we have

substitute the given values in the formula
