Your answer is 0.038
not sure if thats correct if its not im really sorry
The triangles r the same so that’s y it’s equal lol
Answer:
Step-by-step explanation:
We want to solve for x in 
You need to group and combine like terms and write in standard form:
By comparing to 
, we a=1,b=-2 and c=-46
The solution can be obtained using the quadratic formula.
We substitute the coefficients to get:
The last choice is correct
The surface area of a sphere is given by the formula
.. A = 4π*r^2
.. A = 4π*(1.25 in)^2 ≈ 20 in^2
When there are no special grouping symbols, math problems are solved from left to right. Although there are other important rules about the order in which you do the operations (addition/subtraction/multiplication/division) in a math expression or equation, this lesson will focus on grouping symbols. The rest of the order of operations rules will be explained in the Determining Order of Operations lesson. To help prevent confusion as you learn how to use the grouping symbols, this lesson will only use addition and subtraction.
