Answer:
(16x² - 72x + 85) / (4x-9)
Step-by-step explanation:
first put g(x) into h(x)
h(g(x)) = 4(x-2) - 1 = 4x - 8 - 1 = 4x - 9, then
f(h(g(x))) = (4x - 9) + (4/4x-9) = ((4x-9)(4x-9) + 4)/(4x-9) =
(16x² - 72x + 81 + 4)/(4x-9) = (16x² - 72x + 85)/(4x-9)
If you are missing parentheses around (x+4)/x, then the answer would be different.
Answer: 45 mph
Step-by-step explanation:
We know that Rob was driving 63 mph which is 18 miles faster than pigeons, therefore you subtract to get the answer.
63-18=45
Answer:
m∠QRT = 90°
m∠QRT = m∠SRT
Step-by-step explanation:
Triangle QST is isosceles with QT ≅ ST. In isoscels triangle QST, angles STR and RTQ are congruent.
RT is angle T bisector, so angles QTR and STR are congruent.
Consider two triangles QTR and STR. In these triangles:
- TR ≅ TR (reflexive property);
- ∠QTR ≅ ∠STR (given);
- QT ≅ ST (given).
By SAS postulate, these two triangles are congruent. Two congruent triangles have congruent corresponding sides, so
Angles QRT and SRT are supplementary (add up to 180°). Since these two angles are congruent, they have the same measure equal to 
So, true options are
m∠QRT = 90°
m∠QRT = m∠SRT
