You have to factor by grouping.
(4a - 5) (a + 4)
Answer is B) JK=9 and KL=10
you subtract 7 from 26 to get 19
Answer:
T = 88 degrees to the nearest degree
Step-by-step explanation:
To find the measure of the angle T, we can use the cosine rule
We have the formula as;
t^2 = u^2 + v^2 - 2uv Cos T
t = 8.1
u = 7.1
v = 4.2
8.1^2 = 7.1^2 + 4.2^2 - 2(7.1)(4.2) cos T
-2.44 = -59.64 cos T
cos T = (2.44)/(59.64)
T = arc cos (2.44/59.64)
T = 87.66
to the nearest degree, this is 88 degrees
Solution:
<u>It should be noted:</u>
- If the starting point of the inequality is half shaded, the sign will be < or >.
- If the starting point of the inequality is fully shaded, the sign will be ≤ or ≥.
<u>We can tell that:</u>
- The inequality will either have an < or > sign.
- The blue line tells us that the value of x must be greater than -1.
This clearly tells us that the inequality is x > -1
<u>In conclusion:</u>
Option C is correct.
