Answer:
• x = -4, x = 0, x = 1
Step-by-step explanation:
x is a factor of all terms, so x=0 is a zero. (Eliminates choices 1 and 5.)
The sum of coefficients is 0, so x=1 is a zero. (Eliminates choices 3 and 4.)
Reversing the sign of the odd-degree terms gives signs of -++, so there is one sign change, hence one negative real root (by Descartes' rule of signs). This confirms choice 2 as the answer.
___
Of course, your graphing calculator can answer this almost as quickly.
Answer:
i am so sorry if its wrong
Each of the triangles making up the sides and base have a base of 8 cm and a height of 6.9 cm. Then the area of the pyramid is that of 4 such triangles.
A = 4×(1/2)×b×h
A = 2×(8 cm)×(6.9 cm)
A = 110.4 cm²Step-by-step explanation:
It’s in the Millions place
To go to kite 2, kite 1 must go up 6 then 6 to the left
The rule x + 6, y - 6.
so for the 1st one triangle is 8
diamond is 3
and star is 11
the second one star is 5
diamond is 5
and triangle is 2 again
and for the last one well try to do it yourself and if you cant do it comment on this =)
