Answer:
1)
32x^2 - 28x - 15
2)
30x^2 + 54x - 12
Step-by-step explanation:
1.
(8x+3)(4x-5)
Using FOIL
= (8x)(4x) + (8x)(-5) + (3)(4x) + (3)(-5)
= 32x^2 - 40x + 12x - 15
= 32x^2 - 28x - 15
2.
(10x-2)(3x+6)
Using FOIL
= (10x)(3x) + (10x)(6) + (-2)(3x) + (-2)(6)
= 30x^2 + 60x - 6x - 12
= 30x^2 + 54x - 12
Answer:
144
Step-by-step explanation:
<u>Step 1: Convert 4 yards into feet</u>
1 yard = 3 feet
4 * 3 = 12 feet
<u>Step 2: Convert 12 feet into inches</u>
1 foot = 12 inches
12 * 12 = 144 inches
Answer: Bobby can cut 144 1-inch strips.
Tan(34) = a/700
a = 700*tan(34) =472.155 so 472
The answer is 286.
y = 70 + 18(x)
x = 12
y = 70 + 18 * 12
y = 70 + 216
y = 286
