Answer:
-6
Step-by-step explanation:
Use PEMDAS. Parenthesis. Exponents. Multiplication. Division. Addition. Subtraction. there are no parenthesis so that doesn't matter. there are no exponents. but there is multiplication. 8×7 = 56. so now the equation is 56+4×2-11-7×4. you still have multiplication so now we do 4×2 which is 8. the equation is now 56+8-11-7×4. you still have multiplication so now do 7×4 which is 28. the equation is now 56+8-11-28. there is no multiplication. or division. next is addition. 56+8 which is 64. now the equation is 64-11-28. next you do subtraction. 64-11 which is 53. now the equation is 53-28 which is 25. 25 is the answer. I hope this helped ☺️
Answer:
.9 or 90%
.1 or 10%
Step-by-step explanation:
E= Exam
P=Paper
E= .71
P= .45
E∩P=.26
A.) E∪P=?
E∪P= E+P-E∩P
.71+.45-.26= .9
B.) E'∩P' = (E∪P)'
(E∪P)' = 1-.9 = .1
-2w (w + 8)
Assuming that it is a polynomial from which you must find the roots, we must first rewrite it:
-2w (w + 8) = 0
The roots are then:
w1 = 0
w2 = -8
Assuming you only have to rewrite the expression, the answer is:
-2w ^ 2 -16w
Answer:
w1 = 0
w2 = -8
-2w ^ 2 -16w
