When –3 is multiplied by the sum of a number and 8, the result is –21. Find the number.

kumpel [21]

-3 times (x+8)=-21
-3(x+8)=-21
distributive property=a(b+c)=ab+ac
-3(x+8)=-3x+(-3)(8)=-3x-24
-3x-24=-21
add 3x to both sides
-24=-21+3x
add 21 to both sides
-3=3x
divide both sids by 3
-1=x

x=-1

If a = x+21, b = 4, c = x + 3, and d = 10, then the value of x =

Alex

Using the intersecting chord theorem:

a x b = c x d

x+21 * 4 = x+3 * 10

Simplify:

4x+84 = 10x+30

Subtract 30 from both sides:

4x + 54 = 10x

Subtract 4x from both sides:

54 = 6x

Divide both sides by 6:

x = 9
