Answer:
area of triangle =1/2×perpendicular×base
35m²×2=(g-11)(g-8)
70=g(g-8)-11(g-8)
70=g²-8g-11g+88
70=g²-19g+88
0=g²-19g+88-70
0=g²-19g+18
g²-18g-g+18=0
g(g-18)-1(g-18)=0
(g-18)(g-1)=0
either
g=18
or
g=1
Step-by-step explanation:
base=18-8=10m
perpendicular=18-11=7m
Answer:
the answer is 97
Step-by-step explanation:
Distance to the cabin is 'D' .
Distance = (speed) x (time)
Distance going = 30 H
Distance coming back = 36 (H - 1)
Distance is the same in both directions.
30H = 36(H - 1)
Eliminate parentheses: 30H = 36H - 36
Add 36 to each side: 30H + 36 = 36H
Subtract 30H from each side: 36 = 6H
Divide each side by 6 : 6 = H
It took 6 hours to go, 5 hours to come back,
and the trip was 180 miles each way.
6 x 30 = 180
5 x 36 = 180 yay !
Notice that 180 is the least common multiple (LCM)
of 30 and 36 . I'll bet that could have helped us if
we were all wide awake when we read the question.
Answer:
240
Step-by-step explanation:
4c2 + 7c – 5 = 0 a=4 b=7 c=-5
x = [-b +-sq root (b^2 -4ac)] / 2a
x = [-7 +-sq root(7^2 -4*4*-5)] / 2*4
x = [-7 +-sq root(49 + 80)] / 8
x = [-7 +-5.5677643628] /8
x1 = 0.544727125
x2 = -2.294727125
