Since the base is a regular quadrilateral, each of its 4 sides must have length
s = P/4
s = (60 cm)/4 = 15 cm
The area of one lateral face is the product of side length and height.
A = s×h
105 cm² = (15 cm)×h
Then the height of the prism is
h = (105 cm²)/(15 cm) = 7 cm
The area of the base is then
B = s²
B = (15 cm)² = 225 cm²
The volume of the prism is the product of its base area and height.
V = Bh
V = (225 cm²)×(7 cm) = 1575 cm³
The volume is 1575 cm³.
<em>Answer:</em>
<em>(r + 9)(r - 3)</em>
<em>Step-by-step explanation:</em>
<em>r² + 6r - 27 =</em>
<em>= r² + 9r - 3r - 27</em>
<em>= r(r + 9) - 3(r + 9)</em>
<em>= (r + 9)(r - 3)</em>
First one is A
Second one is also A
the third one is also A!!!!
DA, AB, BC, CD
square, are side equal length and 90 degree angles
rectangle, two pairs of same length and 90 degree angles
parallelogram, two pairs of same length and two pairs of same angles
rhombus, all sides equal, two pairs of same angles.
yes, because they have the same length of all sides, same shape and same angles.
hope that helps! :D
Answer:
536.52
Step-by-step explanation:
5.26x102=536.52
Answer: x=-3
Step-by-step explanation:
So we can say 2 square/3 square to whole power 4= 4/9 to the whole power 1, so -7*1=-7
2x-1=-7
x=-3
