Step-by-step explanation:
Answer:
step 2; a negative times a negative = a positive.
Step-by-step explanation:
-4(6-b)=4
<u>-24 </u><u>+</u><u>4b=4</u>
4b=28
b=7
Step-by-step explanation:
(1 - cos²A) (1 + tan²A) = tan²A
(sin²A)(sec²A) = tan²A
(sin²A)(1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → <u>Proved</u>
