Answer:B
Step-by-step explanation:
4x2 =121
4x2-121=0
using the general formula
[-b( +/-) √b2-4ac]/2a
a=4, b= 0, c=-121
x= [0 ( +/-)√02-(4*4*-121)]/2.4
= ( +/-)√1936)/8 = ( +/-)5.5
x =5.5
x = -5.5
Answer:
z= - 5
√
38
Step-by-step explanation:
take the root of both sides
or
you can factor each set and make them equal to zero
If it was one year it would be 2200 and you just keep adding 200 for each year.
Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
Area of a rectangle = length × width
Since we are finding the length of the rectangle

From the question
area = 5/8 square yards
width = 3/4 yard
So we have

We have the final answer as

Answer:
m∠XMN = 80°
Step-by-step explanation:
you know that:
4x + 5 + 6x - 10 = 145
solve for x:
10x - 5 = 145
10x = 150
x = 15
Use this information to solve for m∠XMN
6(15) - 10
90 - 10
80
m∠XMN = 80°
