Hello!

You solve this algebraically

x^2 - 100 = 0

Add 100 to both sides

x^2 = 100

Take the square root of 100

When you take a square root the solutions are the number positive and negative

x = 10
x = -10

The answer is C. x = 10, -10

Hope this helps!

Solve for x. Enter your answer below as an improper fraction in lowest terms,
ICE Princess25 [194]

Answer:

x = \frac{83}{36}

Step-by-step explanation:

Given

x - 2 \frac{1}{4} = \frac{1}{18} ( change mixed number to improper fraction )

x - \frac{9}{4} = \frac{1}{18}

Multiply through by 36 ( the LCM of 4 and 18 ) to clear the fractions

36x - 81 = 2 ( add 81 to both sides )

36x = 83 ( divide both sides by 36 )

x = \frac{83}{36}

In Δ ABC and ΔXYZ ,∠B=∠X=90 and BC=XZ .What additional information is required to make Δ ABC congruent to ΔXYZ by R.H.S conditio
Pani-rosa [81]

Answer:

AC = XY

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.

Two triangles are said to be congruent if all the three sides and three angles of one triangle is equal to the three sides and three angles of the other triangle.

In Δ ABC and ΔXYZ ,∠B=∠X=90. This means that triangle ABC and triangle XYZ are right angled triangle since one of their angles is 90 degrees.

The hypotenuse is the side opposite to right angle (90 degrees).

Therefore AC is the hypotenuse of triangle ABC and YZ is the hypotenuse of triangle XYZ.

If the hypotenuse and one leg of a right angled triangle is equal to the hypotenuse and leg of another right angled triangle, then the two triangles are congruent by RHS rule.

Since BC = XY, for Δ ABC congruent to ΔXYZ by R.H.S condition, the hypotenuse have to be equal, i.e. AC = XY

A baker had 24 boxes for donuts he ended up making 526 donuts and splitting them evenly between the boxes how many extra donuts
sertanlavr [38]

Answer:

The baker ended up with 22 extra donuts.

Step-by-step explanation:

Since the baker had 24 boxes and made 526 donuts, to split them evenly between the total number of boxes means that we need to divide the number of total donuts by the number of boxes:

526 ÷ 24 = 21 remainder of 22

Since 24 x 21 = 504 and 24 x 22 = 528 and the baker only made 526 donuts, then the most amount of donuts he can use to split them evenly with the total amount of 526 is 504.  526 - 504 = 22, so he has an extra 22 donuts that will not be in boxes.
