Solve for x. Enter the solutions from least to greatest.
(x+7)^2 −49=0

Help plz

Step-by-step explanation:

We are given:

And we want to solve for x.

First, we can add 49 to both sides:

Now, we can take the square root of both sides. Since we are taking an even root, we will need plus-minus. Hence:

Evaluate:

Subtract 7 from both sides:

So, we have two solutions:

Evaluate:

So, from least to greatest, our solutions are:

x=0

Step-by-step explanation:

We can first add 49 to both sides to get (x+7)^2=49

We can then take the square root of both sides and get x+7=7

Subtract 7 to both sides and you get x=0

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
