Answer:
-74
Step-by-step explanation:
f(x) = -2x^2 +8x -10
Let x = -4
f(-4) = -2 ( -4)^2 +8(-4) -10
= -2(16) -32-10
= -32 -32-10
= -74
Answer:
k = 45
The angles are 45 , 45, 90
Step-by-step explanation:
The sum of the angles of a triangle are 180
45+ k+2k = 180
Combine like terms
45+3k = 180
Subtract 45 from each side
45+3k-45 = 180-45
3k = 135
Divide by 3
3k/3 = 135/3
k =45
The angles are 45, k,2k
The angles are 45 , 45, 90
Answer:
$6 each
Step-by-step explanation:
the first 10 multiples of 3 are 3,6,9,12,15,18,21,24,27,30
3×2=6
6+6=12
65754.6 because the 9 in the hundreds place bumps up the five in the tenths
Step-by-step explanation:
117+114= 231
360-231= 129
Now find two numbers that add up to 129
