Answer:
0.9 inches
Step-by-step explanation:
The sides of right triangles follow the Pythagorean Theorem:
a² + b² = c²
"a" and "b" are the two shorter sides and "c" is the hypotenuse, the longest side.
Let's plug in what we know.
a² + b² = c²
(1.2)² + b² = (1.5)²
Let's solve the exponents.
1.44 + b² = 2.25
Subtract 1.44 from both sides.
b² = 0.81
Take the square root of both sides.
√b² = √0.81
b = 0.9
The second side will be 0.9 inches.
Each person would have 4/3 of a pizza, or C.

Answer:
B
Step-by-step explanation:
12x² - 157x - 40
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 12 × - 40 = - 480 and sum = - 157
The factors are + 3 and - 160
Use these factors to split the x- term
12x² + 3x - 160x - 40 ( factor the first/second and third/fourth terms
= 3x(4x + 1) - 40(4x + 1) ← factor out (4x + 1) from each term
= (4x + 1)(3x - 40) ← in factored form → B
