Answer:
1944x^2.
Step-by-step explanation:
sqrt 2x^2 * sqrt18^5
= sqrt2x^2 * (sqrt(9^5*2^5))
= sqrt 2 x^2 * (sqrt9^5 * sqrt 2^5)
= sqrt2 x^2 * (243* sqrt2^5)
= 2^0.5 (243 * 2^2.5) x^2
= 2^3 * 243 x^2
= 1944x^2.
Answer:
87
Step-by-step explanation:
f(x)=19x+11
Let x = 4
f(4) = 19*4 +11
=76 +11
= 87
Answer:
<em>The number is -6.</em>
Step-by-step explanation:
Let x = the unknown number
"the sum of a number and four" = n + 4
"Six times the sum of a number and four" = 6(n + 4)
"Six times the sum of a number and four is -12." is the equation
6(n + 4) = -12
Divide both sides by 6.
n + 4 = -2
Subtract 4 from both sides.
n = -6
16 minutes and 15 seconds.
4x2=8 8 days = 14 minutes
7/4=1.75= 2 minutes 15 seconds= total of 16min 15sec
Answer:
No Solution
Step-by-step explanation:
There is no solution because the sq.root of -32 is a imaginary number, you can't have a square root of a negative number.
