Hello from MrBillDoesMath!
Answer:
Choice E and F
Discussion:
From the quadratic formula with a = 3, b = -1, and c = 6
x = ( -b +\- sqrt(b^2 - 4ac) ) / (2a) => substitute in a,b,c from above
x = ( -(-1) +\- sqrt((-1)^2 - 4(3)(6)) / (2*3) => discriminant = 1 - 72 = -71)
x = ( 1 +\- sqrt(-71))/ 6
which are choices E and F
Thank you,
MrB
Hi Briana.
All triangles have a total internal measurement of 180 degrees from their angles. Isosceles triangles have two similar side lengths, and one different side length also known as the base. Considering we have the base, we can determine the side lengths by using the following equation:
2x + 24 = 96
Let's get to solving!
2x + 24 = 96; subtract 24 from both sides.
2x = 72; divide both sides by 2 to solve for the measurement of each side length.
x = 36;
Your answer is B.) 36
I hope this helps!
The largest number in the chart is 45, so the person left 45 minutes after 10:30 a.m. That person left the library at 11:15 a.m.
The area of a 2D form is the amount of space within its perimeter. The correct option is D.
<h3>What is an area?</h3>
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The area of the L block will be the sum of the area of A and B. Therefore, the area can be written as,
Area of L block = Area of A + Area of B
= (7×2) units² + (1 × 5) units²
= 14units² + 5units²
= 19units²
Hence, the correct option is D.
