For a <span>system of two linear equations to have more than one
solution, the lines representing the equations must coincide, i.e. must
be the same or a multiple of each other. In that case, the system will have infinitely many solutions.

do you have a z table chart to look at?
find Z= 0 should show that z=0 = 0.500
and z=2.16 = 0.9846
subtract them
0.9846-0.500 = 0.4846 is the area
Answer:
3466.64 (≈ 3467) cm²
Step-by-step explanation:
A = 2B + 2 sides and floor
A = 2 * (14 * 24) / 2 + 2 * (45 * √14² + 24²) + 45 * 14
A = 336 + 2500.64 + 630 = 3466.64 (≈ 3467)
Answer: C) similar, SAS similarity, triangle LQR
==============================================
Explanation:
The vertical angles KLJ and QLR are congruent. This forms the "A" in "SAS". The angles in question are between the marked sides.
KL = 18 is twice that of QL = 9, or put another way, KL/QL = 18/9 = 2. The ratio of the sides is 2. Also, JL/RL = 16/8 = 2 is the same ratio. Because both pairs of sides have the same ratio, the sides are in proportion. This helps form the two "S" letters of "SAS".
The original triangle has LKJ mentioned at the top. Note the order as its important. We start with L and move to K, so LK is the first segment mentioned. LK = 18 pairs up with LQ = 9, meaning that LQ must be the first segment mentioned of the answer triangle. Therefore LQR is the correct letter sequence if we start with point L. Writing QLR is not correct because Q is the first letter here but Q does not pair up with L.
