H(x)=2x2+x-10
2x²+x-10=0
(2x+5)(x-2)
x=-5/2
x=2
1)
h(x)=2x²+x-10
h(-5/2)= 2(-25/4)+[-5/2]-10
h(-5/2)=-25
2).
h(x)=2x²+x-10
h(2)=2(2)²+2-10
h(2)=8+(-8)
h(2)=0
Answer:
Step-by-step explanation:
In this geometry, the triangles are similar. That means corresponding sides are proportional:
short side/long side = x/10 = 10/25
x = 100/25 = 4 . . . . multiply by 10
__
hypotenuse/short side = y/x = (x+25)/y
y² = 4(29) = 116 . . . . . use 4 for x; cross multiply
y = √116 ≈ 10.8
Answer:
100 is correct answer
Step-by-step explanation:
when ever anything ² , it means that number is multiplied by itself.
in above we multiple 10 with 10 and we get 100.
hope it helped you:)
