7 0

Answer:

x = 4

Step-by-step explanation:

as it is parallelogram opposite sides are equal

so14x -7= 10x-9

14x-7+9=10x

14x -16 = 10x

14x -10x = 16

4x =16

x = 16/4

x = 4

also u can put x = 4 in both expressions and u will get answer of both 49

Evaluate the given expression. Do not use a calculator<br> (5/4)^(-4)
insens350 [35]
When something has a negative power you must move it to the denominator to give it a positive power therefore this would then turn into 1/[(5/4)^4]  to simplify this (5/4)^4 would be (25/16)(25/16) then finally (625/256) so it would then look like this 1/(625/256) in order to not have a fraction in the denominator you would multiply; 1 x (256/625) which is 256/625.

Factor the expression.<br> x^3+8
Aneli [31]
X^3+8
= x^3+2^3

<span>a^3 + b^3 = (a + b)(a^2 – ab + b^2)</span> 

so

x^3+8 
= x^3+2^3
= (x+2)(x^2-2x+2^2)
= (x+2)(x^2-2x+4)
