When your finding square roots all you need to do is find what same numbers multiply up to that number, you did the square root of 49 correctly but the square root of 34 is 5.83 and the square root of 45 is 6.70.
and the division does that say 13 divded by 7?
Answer:
It should be C
Step-by-step explanation:
Substituting in a value of x,
4 * ( 1/2 )^x 4 * ( 1/2 )^x
= 4 * ( 1/2 )^ 2 = 4 * ( 1/2 )^ -2
= 4 * 1/4 = 4 * 4
= 1 = 16
C checks out, and all the other options don't equal to the values on the table.
Given:
Consider the number as <em>x</em>.
The objective is to represent algebraic expression for, 2 is subtracted from the square of a number.
Explanation:
Since the number is given as <em>x</em>, the square of the number can be represented as,

Now, subtract 2 from the above expression,

Hence, the required expression is x²-2.
Answer:
26 is the answer
Step-by-step explanation:
y=4x+2. eq1
y=5x. eq2
4x=2-y
x=(2-y) /4
substitute in equation 2
y=5(2-y) /2
y=(10-5y)/2
4y=10-5y
9y=10
y=10/9
substitute in equation 2 or 1
substituting in equation 2
10/9=5x
x=10/45
x=10/45 y=10/9
you can verify it also.
