66 minutes is the correct answer
-3x-2y=30
-2y=3x+30
y=-3/2x-15
the answer is y=-3/2x-15
Pablo can make 5 arrays because there are 9 factors of 36 plus a square number so that means 10 factors so you divide that by 2 since you can't have any arrays with the same factor.
Answer:
Total area = 51 in²
Step-by-step explanation:
Section the shape into a rectangle and a triangle.
Area of a rectangle = width x length
⇒ area = 6 x 7 = 42 in²
Area of a triangle = 1/2 x base x height
⇒ area = 1/2 x (6 - 3) x (13 - 7) = 9 in²
Total area of composite shape = 42 + 9 = 51 in²
Answer:
8. 12.8
9. 400
Step-by-step explanation:
8. look at it like a square with a rectangle cut out of it, 4*4 = 16, the rectangle needs a base and to find that base 1.5+0.9 = 2.4, 4-2.4 = 1.6, 1.6*2 = 3.2, 16-3.2 = 12.8
9. look at it like a trapezoid with a triangle cut out of it, add the to bases 14+32 = 46, 46*20 = 920 divided by 2 which is 460, and then area subtract the triangle 12*10 = 120 divided by 2 which is 60, so 460-60 = 400
