Answer:
72 ft²
Step-by-step explanation:
If the width is 50% the length, thats a width of 6 feet as 12*0.5=6, then you multiply 6 and 12 to get the area of 12
Answer:
k = 15
Step-by-step explanation:
12/4/5 = 4/5/4/5 k
15 = k
OR
5/4 (12) = 4/5 (5/4) k (multiply by the reciprocal)
15 = k
Answer:

y value divided by x value for slope, then use desmos
Answer:
y=x-4
Step-by-step explanation:
Answer:
3 (x + 2)(3x + 5)
Step-by-step explanation:
Given
9 + 33 + 30 ← factor out 3 from each term
= 3 (3x² + 11x + 10) ← factor the quadratic
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 = 3 × 10 = 30 and sum = + 11
The factors are 6 and 5
Use these factors to split the x- term
3x² + 6x + 5x + 10 ( factor the first/second and third/fourth terms )
= 3x(x + 2) + 5(x + 2) ← factor out (x + 2) from each term
= (x + 2)(3x + 5), thus
3x² + 11x + 10 = (x + 2)(3x + 5)
and
9 + 33 + 30 = 3 (x + 2)(3x + 5)
