I have an answer and explanation but I can't type so search up the question you asked and you should get an answer and explanation from s0cratic.

**Answer:**

-65d

**Step-by-step explanation:**

(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

Now write all the terms together

Combine like terms

HEre -65d is missing

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

-65d=-65d.

-65d=-65d.

**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

f(x)=-2x^2-7x+6

Find f(−3)

**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.

**Answer:**

42

**Step-by-step explanation:**

Complete the statements to solve for x.

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

Substitute the expressions into the proportion: StartFraction x minus 5 Over x EndFraction = StartFraction x minus 3 Over x + 4 EndFraction.

Cross-multiply: (x – 5)() = x(x – 3).

Distribute: x(x) + x(4) – 5(x) – 5(4) = x(x) + x(–3).

Multiply and simplify: x2 – x – = x2 – 3x.

Solve for x: x = .

**Answer:**

x = 10

**Step-by-step explanation:**

By the converse of the side-splitter theorem, if , then KM ∥ JN.

Substitute the expressions into the proportion:

Cross-multiply:

(x – 5)(x+4) = x(x – 3).

Distribute:

Multiply and simplify:

Solve for x: **x = 10**

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

**Answer:**

**What value of x would make KM ∥ JN?**

**Triangle J L N is cut by line segment K M. Line segment K M goes from side J L to side L N. The length of J K is x minus 5, the length of K L is x, the length of L M is x + 4, and the length of M N is x minus 3.**
