Answer:
The length of the base edge is 3 cm
Step-by-step explanation:
Volume of square pyramid =![\frac{1}{3}BH](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7DBH)
Where B = area of square base
H = Height
Let the length of base edge be x
Area of base = ![Side^2 = x^2](https://tex.z-dn.net/?f=Side%5E2%20%3D%20x%5E2)
Height of pyramid = 5 cm
So,Volume of square pyramid =![\frac{1}{3}BH=\frac{1}{3} \times x^2 \times 5](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7DBH%3D%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%20x%5E2%20%5Ctimes%205)
We are given that The volume of a square pyramid is 15 cubic centimeters.
So,![\frac{1}{3} \times x^2 \times 5=15](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20%5Ctimes%20x%5E2%20%5Ctimes%205%3D15)
![x^2 = \frac{15 \times 3}{5}](https://tex.z-dn.net/?f=x%5E2%20%3D%20%5Cfrac%7B15%20%5Ctimes%203%7D%7B5%7D)
![x=\sqrt[2]{\frac{15 \times 3}{5}}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B2%5D%7B%5Cfrac%7B15%20%5Ctimes%203%7D%7B5%7D%7D)
x=3
Hence the length of the base edge is 3 cm
Answer:
false
Step-by-step explanation:
first shape is square
second one is rectangle
so they are not the same
Answer:
No, and this isn't the place to put an ad
Step-by-step explanation:
X^2-7x+38=5x+3
x^2-7x+38-5x-3=5x+3-5x-3
x^2-12x+35=0
Factoring:
(x-5)(x-7)=0
Two solutions:
x-5=0→x-5+5=0+5→x=5
x-7=0→x-7+7=0+7→x=7
Answer: x=5 and x=7
Answer: Options B. 7 and D. 5
