Answer:
The median height of Sam and his brothers is 135.
Step-by-step explanation:
First, let's find the age of Sam's brothers:


The median height of Sam and his brothers is given by the middle number of the three values arranged from lowest to highest:
133 <u>135</u> 140
<em>Since the middle number is 135, then the median height is 135. </em>
Therefore, the median height of Sam and his brothers is 135.

Answer:
D
Step-by-step explanation:
given a quadratic equation in standard form
ax² + bx + c = 0, then the discriminant is
Δ = b² - 4ac
x² + 3x - 4 = 0 ← is in standard form
with a = 1, b = 3, c = - 4
b² - 4ac = 3² - (4 × 1 × - 4) = 9 - (- 16) = 9 + 16 = 25 → D
Answer:
First blanks: 36 and 36
Second blanks: -7 or 7
Step-by-step explanation:
Simplify (x+6)^2 and you get x^2+12x+36. 36 is what’s missing in that blank, and it needs to be added to both sides. Next, the second set of blanks is what you get when you take the square root of both sides of the equation. Sqrt((x+6)^2)=x+6. Sqrt(49)= -7 or 7. So you have to put 7 and -7 in the second set of blanks.
