2x2 - 6x + 7 = 0. A) Two rational Solutions B) Two irrational Conjugate Solutions C) One Rational Solutions D) Two Complex/Imaginary ...
Consider the first blank is the green box.
Given:
The equations are


To find:
The value belongs in the green box
Solution:
We have,
...(i)
...(ii)
Adding (i) and (ii), we get



So, the value for the first black is 2x. It means the value belongs in the green box is 2x.
The values of three blanks are 2x, 0 and 13 respectively.
Therefore, the correct option is B.
Answer:
24179 square inches
Step-by-step explanation:
In ΔRST, r = 620 inches, s = 840 inches and t=230 inches. Find the area of ΔRST to the nearest square inch.
We use the formula
Heron's formula = √s(s - a)(s - b)(s - c)
Where s = a + b + c/2
Solving for s
s = 620 + 840 + 230/2
s = 845
Solving for the area of the triangle
= √845 × (845 - 620) × (845 - 840) × (845 - 230)
= √584634375
= 24,179.213696893 square inches
Approximately = 24179 square inches
The measure of YZ is 3.4 cm and the measure of c is 1.7 cm.
Given that, Y is between X and Z. XY = 5.5 , YZ = 2c , X Z= 8.9.
We need to find the value of c and YZ.
<h3>What is a line segment?</h3>
A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions. In this lesson, we will learn more about a line segment, its symbol, and the way to measure a line segment.
Now, YZ=XZ-XY
⇒2c=8.9-5.5
⇒2c=3.4 cm
⇒c=1.7 cm
Therefore, the measure of YZ is 3.4 cm and the measure of c is 1.7 cm.
