I a pretty sure it is 228,000 but i am not sure.
Answer:
Step-by-step explanation:
14.
by pythagoras,s theorem

15.
first perpendicular=y(say)
and second perpendicular=z (say)
y²=9²+7²=81+49=130
z²=y²+5²=130+25=155
x²=z²+4²=155+16=171
x=√(171)
Answer
2
Step-by-step explanation:
(reorder terms)
<u>2x + 2x</u> = 8
collect like terms
<u>4x=8</u>
divide both sides of the equation
x = 2
Answer:
it is 5 if im not mistaken
(3x−2)(2x^2+5)
=(3x+−2)(2x^2+5)
=(3x)(2x^2)+(3x)(5)+(−2)(2x^2)+(−2)(5)
=6x^3+15x−4x^2−10
=6x^3−4x^2+15x−10
