Find the missing coefficient. (5d − 7)(5d − 6) = 25d2 ++ 42 5 65 –5 –65

Answers

Answer:

-65d

Step-by-step explanation:

(5d − 7)(5d − 6)

(5d - 7)(5d - 6)

Multiply it using FOIL method to find the missing term

Multiply 5d inside the second parenthesis and then multiply -7 inside second parenthesis

5d \cdot 5d= 25d^2

5d \cdot -6= -30d^2

-7 \cdot 5d=-35d

-7 \cdot -6=42

Now write all the terms together

25d^2-30d-35d+42

Combine like terms

25d^2-65d+42

HEre -65d is missing

i do believe it is -65d because the equation will look like this in the end
-65d=-65d.

Which model represents the equation 4w+3=3w+6

Answers

Answer:

w=3 (please give me brianliestt!!)

Step-by-step explanation:

4w+3=3w+6 (subtract 3 from both sides)

     -3       -3

4w=3w+3 (subtract 3w on both sides)

-3w  -3w

1w=3 (divide by 1)

w=3

Evaluate the function.
f(x)=-2x^2-7x+6

Find f(−3)

Answers

Answer:

f(-3) = 9

Step-by-step explanation:

Step 1: Define

f(x) = -2x² - 7x + 6

f(-3) = x = -3

Step 2: Substitute and evaluate

f(-3) = -2(-3)² - 7(-3) + 6

f(-3) = -2(9) + 21 + 6

f(-3) = -18 + 21 + 6

f(-3) = 3 + 6

f(-3) = 9

Substituting x = -3 into the function f(x) = -2x^2 - 7x + 6, we get f(-3) = -33. Therefore, the value of the function at x = -3 is -33.

To evaluate the function f(x)=−2x ^2 −7x+6 at  x=−3, substitute  −3 for x in the function: f(−3)=−2{(−3) }^2 −7(−3)+6

Now, calculate each part of the expression:

(−3) ^2   is 9  because the square of  −3 is  9.

−2 times 9 is  −18 because −2⋅9 =−18.

−7 times −3 is  21 because −7⋅−3=21.

Now, plug these values back into the expression:

f(−3)=−18−21+6

Finally, add and subtract:

f(−3)=(−18−21)+6=−39+6=−33

So, f(−3)=−33.

The value of the function

f(x)=−2x^ 2 −7x+6 at  x=−3 is  −33.

Answers

Answer:

x = 10

Step-by-step explanation:

By the converse of the side-splitter theorem, if (JK)/(KL)= (NM)/(ML) , then KM ∥ JN.

Substitute the expressions into the proportion:

(x-5)/(x)= (x-3)/(x+4)

Cross-multiply:

(x – 5)(x+4) = x(x – 3).

Distribute:

x(x) + x(4) - 5(x) - 5(4) = x(x) + x(-3).

Multiply and simplify:

x^2 +4x- 5x - 20 = x^2-3x\n-x-20=-3x\n$Collect like terms$\n-x+3x=20\n2x=20\n$Divide both sides by 2\nx=10

Solve for x: x = 10

Therefore, the value of x that would make KM parallel to JN is 10.
