False.
Step-by-step explanation:
A multiple of a number is that number multiplied by an integer.
Answer:
9
Step-by-step explanation:
.9*10=10
it's basically simple multiplication with a decimal
Answer:
x^4 - 81 = 0
(x² - 9)(x² + 9) = 0
Notice that the first of these is itself a difference of two squares:
(x - 3)(x + 3)(x² + 9) = 0
So the solutions are x = 3, x = -3, x = 3i, x = -3i
Answer:
I believe it could be any number because:
let y=any number
x^2+10x+y=16+y
x^2+10x+y-y=16+y-y
x^2+10x=16
you can add any number to both side and not change the solution.
Answer:
The height of the model is 138 cm.
Step-by-step explanation:
Simply multiply the height by the scale factor.
230*0.006
= 1.38 m
We need to convert this measure to centimeters. Centimeters are 1/100 of a meter. Therefore, we can multiply 1.38 meters by 100 to find how many centimeters it is equal to.
1.38*100 = 138
The height of the model is 138 cm.
