Answer:

5) x = 77

7) b = 210

Step-by-step explanation:

5) 11 = X/7

multiply both sides by 7. doing this gets rid of the 7 on the right side of the equation.

(7)(11) = x

77 = x

7) 14 = b/15

same thing as above! multiply both sides by 15.

(15)(14) = b

210 = b

Hope this helps you!

Super confused definitely need help on this

Answer:

$(x-5)(x+8)=x^2+3x-40$

Step-by-step explanation:

So we have the expression:

$(x-5)(x+8)$

To multiply, distribute the left to the terms on the right:

$=(x-5)(x)+(x-5)(8)$

Distribute:

$=(x^2-5x)+(8x-40)$

Combine like terms:

$=(x^2)+(-5x+8x)+(-40)$

Simplify:

$=x^2+3x-40$

Therefore:

$(x-5)(x+8)=x^2+3x-40$

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER

professor190 [17]

Answer:

Step-by-step explanation:

The formula for the Pythagorean Theorem is:

$\sqrt{a^2+b^2}=c$

Now,

A=7

B=24

7x7=49

24x24=576

Add,

576+49=625

Last,

Take the square root of 625

The square root of 625 is 25

c=25

To Check if the hypotenuse is correct:

$a^2+b^2=c^2$

$7^2+24^2=25^2$

7x7=49

24x24=576

25x25=625

49+576=625

625=625,

Therefore the hypotenuse is 25.
