Answer:
Step-by-step explanation:
Write the number in exponential form with the base of 2:
Since the bases are the same, set the exponents equals.
Cancel equal terms on both sides of the equation:
Answer:
Step-by-step explanation:
hello :
x² - 9x = 0
x(x-9)=0
x=0 or x-9=0
x=0 or x= 9
(5 + x) / 6 = -1....multiply both sides by 6, cancelling out the 6 on the left side
5 + x = -1 * 6
5 + x = -6
x = -6 - 5
x = -11
Volume of a pyramid is (L * w * h) / 3
L=10 and w=10
h can be found by using the Pythagorean theorem:
divide the base by 2 and we get 5. Then we have that the hypotenuse is 13 and the bottom of the right triangle we formed is 5. a= sqrt(c^2-b^2)
a=h=12
we plug these numbers into the formula for the volume of a pyramid and get:
400
Answer:
60
Step-by-step explanation:
y+y+60=180
2y =120
therefore,y=60
