Answer: x = 5, x = -7/2
<u>Step-by-step explanation:</u>
2x² - 3x - 35 = 0
<u>Step 1:</u> Find two values whose product = 2(-35) and sum = -3: -10 & 7
<u>Step 2: </u>Replace the b-value of -3x with -10x + 7x:
2x² - 10x + 7x - 35 = 0
<u>Step 3:</u> Factor the first two terms and the second two terms:
2x(x - 5) +7(x - 5) = 0
<u>Step 4</u>: Write the factored form:
Notice that the parenthesis are identical. This is one of the factors. The outside values are the other factor:
Parenthesis: (x - 5)
Outside: (2x + 7)
Factored form: (x - 5)(2x + 7) = 0
<u>Step 5: </u>Set each factor each to zero and solve for x:
x - 5 = 0 2x + 7 = 0
x - 5

Answer:
C?
Step-by-step explanation:
A) Jared makes x of a goodie bag per hour. How many
can he make in y of an hour?
B) Jared makes x of a goodie bag per hour. How many
can he make in y of an hour?
C) Jared has x of an hour left to finish making goodie bags. It takes him y of an hour to make each goodie bag. How many goodie bags can he make?
D) id k
Quotient is the answer to a division problem, so we need to find a problem that needs to divide x and y to find the answer. It isn't A or B, since they are asking for y, not the quotient. I have no idea what D is. C makes sense, so C might be the answer.
It tells us how much time he has(x), and how long it takes him to make 1 bag(y), and we need to find the answer, which is the quotient.
So C is the answer.

The operation which you should do first in the Simplification of the expression -3(-5) - 16 is -3 times -5. option A
Simplification
Based on the principle of BODMAS
B = Bracket
O = of
D = Division
M = Multiplication
A = Addition
S = Subtraction
-3(-5) - 16
open parenthesis
= 15 - 16
= -1
Therefore, the operation which you should do first in the Simplification of the expression -3(-5) - 16 is -3 times -5. option A
