Answer:
0
Step-by-step explanation:
-7+1+ -1 * -6
Using PEMDAS, we multiply and divide first
-1*-6 = 6
Then we add and subtract from left to right
-7+1+ 6
-6+6 =0
Answer:
That can be re-written:
x^2 + 5x -8 = 0
We use the Quadratic Formula
a=1
b = 5
c = -8
x = [-b +- sq root (b^2 - 4ac) ] / 2a
x = [-5 +- sq root (25 - - 32)] / 2
x1 = [-5 + sq root (57)] / 2
x1 = 1.27491722
x2 = [-5 - sq root (57)] / 2
x2 = -6.2749172176
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
First, subtract 8 from 143 which would give you 135. You then divide 135 by 5 and you get 27
Given:
In triangle OPQ, o = 700 cm, p = 840 cm and q=620 cm.
To find:
The measure of angle P.
Solution:
According to the Law of Cosines:

Using Law of Cosines in triangle OPQ, we get




On further simplification, we get




Therefore, the measure of angle P is 79 degrees.
