Answer:

6. (a-4)(a+9)

7. (3p+4)(p-2)

8. Will explain below.

9. (5b+4)(5b-4)

Step-by-step explanation:

HELLOOO IM BACK

6. -4*9 = -36 (the variable), 9-4 = 5 (a) , so a^2 +5a - 36 is fulfilled.

7. 4*-2 = -8, 4-2 = 2, so 3p^2 - 2p - 8 is fulfilled.

9. 25b^2 = (5b)^2

16 = 4^2

Using the difference of squares formula, a^2-b^2= (a+b)(a-b)

HELPPP I NEED TO DO THIS BEFORE 7:00​
Oksana_A [137]

Answer:

A, (13/3 x 5/13)

Step-by-step explanation:

So first, you should change the mixed numbers into improper fractions.  To convert, just multiply the whole number by the denominator and add the numerator.  Do that to both fractions and you should get 13/3 ÷ 13/5.  Since you need to switch to multiplication, switch the sign and flip that fraction/  That asnwer is 13/3 x 5/13.  Hope that helps!  :)

Find three consecutive integers whose sum is equal to −354. Three consecutive integers in ascending form are __,__,__
mixer [17]

Answer: -119, -120, and -121

Step-by-step explanation: This problem states that the sum of three consecutive integers is -354 and it asks us to find the integers. Three consecutive integers can be represented as followed.

X ⇒ <em>first integer</em>

X + 1 ⇒ <em>second integer</em>

X + 2 ⇒<em> third integer</em>

<em />

Since the sum of our three consecutive integers is -354, we can set up an equation to represent this.

X + X + 1 + X + 2 = -354

Now, we can simplify on the left side of the equation.

3x + 3 = -354

      -3      -3    ← subtract 3 on both sides of the equation

3x = -357

÷3     ÷3     ← divide both sides by 3

X = -119

X ⇒ <em>first integer = </em><em>-119</em>

X + 1 ⇒ <em>second integer = </em><em>-120</em>

X + 2 ⇒<em> third integer = </em><em>-121</em>

<em />

Therefore, our three consecutive integers are -119, -120, and -121.

Solve 4(x-5)= 14 please answer nowww
Anna35 [415]

Answer:

x=8.5

Step-by-step explanation:

To solve this equation, we want to find out what x is. To do this, we need to get x by itself.

Perform the opposite of what is being done to the equation. Remember to perform everything to both sides.

4(x-5)=14

4 is being multiplied by x-5. The opposite of multiplication is division. Divide both sides by 4.

4(x-5)/4=14/4

x-5=14/4

x-5=3.5

5 is being subtracted from x. The opposite of subtraction is addition. Add 5 to both sides.

x-5+5=3.5+5

x=3.5+5

x=8.5

Let's check our solution. Plug 8.5 in for x in the original equation.

4(x-5)=14

4(8.5-5)=14

4(3.5)=14

14=14

Both sides of the equation are the same, so we know our solution, <u>x=8.5 </u>is correct.
