- 2x - 11 = - 25 :) hope this is ok
x2 - 12x - 12 = 0
(x - 6)2 - 48 = 0
(x - 6)2 = 48
Hence, the answer is (B).
Answer:
c., d., f
Step-by-step explanation:
"elana walked 12 miles"
That is 12.
"then she walked 1/4 that distance"
That is 1/4 of 12 miles, so it is 1/4 * 12
She walked altogether
12 + 1/4 * 12 = 12 + 3 = 15
She walked altogether 15 miles.
a.12+1/4 = 12.25 which is not 15
b.12×1/4 = 3 which is not 15
c.12+1/4×12 = 12 + 3 = 15 which is correct
d.12(1+ 1/4) = 12(1.25) = 15 which is correct
e.12×3/4 = 9 which is not 15
f.12×5/4 = 15 which is correct
Answer: c., d., f

Answer:
Height of flag pole to the nearest foot is 43 feet
Step-by-step explanation:
In the diagram we have flag pole AB and C is the point on the ground.
It is given that angle of depression is 30°
and the distance of the point C from the base B is 75 feet
so we have
BC= 75 feet
∠C = 30°
AB= h feet
now in right ΔABC

now we plug AB= h , ∠C= 30° and BC =75

( multiply both sides by 75)

Height of flag pole to the nearest foot is
h= 43 feet
