Answer:
See below.
Step-by-step explanation:
Lets take √72:
Factoring 72 to find perfect squares:
72 = 2*2*2*3*3
The largest perfect square in the above = 2*2*3*3 = 36.
So we can write 72 as 36*2.
√72 = √(36 * 2)
√36 * √2
= 6√2.
One more example:
√18 = √(2*3*3)
= √9*√2
= 3√2.
Answer:
17
Step-by-step explanation:
(8×8) + (15×15) = 289
square root of 289 is 17
Answer: 4
Step-by-step explanation:
All you have to do is multiply each number 14 * 4 = 56 : 16 * 4 = 64 : and 7 * 4 = 28
Answer:
Option b
Step-by-step explanation:
To solve this problem we must test if the function is even.
If f(-x) = f(x) then the function is even and is symmetric with respect to the y-axis.
If f(-x) = -f(x) then the function is odd and has symmetry with respect to the origin.
We have the function:
We make:
Rewriting the function we have
Finally, the function has symmetry with respect to the y axis.
Answer:
Step-by-step explanation:
3x - 5y = -35
2x - 5y = -30
3x - 5y = -35
-2x + 5y = 30
x = -5
3(-5) -5y = -35
-15 - 5y = -35
-5y = -20
y = 4
