Answer:
1332 i think
Step-by-step explanation:
287+379=666
666*2=1332
Answer:
70 and 71
Step-by-step explanation:
Consecutive means in a row
x is the first number
x+1 is the next number
x+ x+1 = 141
Combine like terms
2x+1 =141
Subtract 1 from each side
2x+1-1=141-1
2x= 140
Divide each side by 2
2x/2 =140/2
x = 70
The two lockers are 70,71
well, first off, let's notice that we have a trapezoid with a rectangle inside it, so the rectangle is really "using up" area that the trapezoid already has.
now, if we just get the area of the trapezoid, and then the area of the rectangle alone, and then subtract that area of the rectangle, the rectangle will in effect be making a hole inside the trapezoid's area, and what's leftover, is the shaded section, that part the hole is not touching.
Are you looking to simplify it? If so I think the answer would be 1/2.
Answer:
For the rectangle
Length=ℓ
Breadth=b
Area is 12 cm2
ℓb=12
Perimeter is 16 cm
2(ℓ+b)=16
ℓ+b=8
Substitute b=12ℓ from first equation
ℓ+12ℓ=8
ℓ2+12=8ℓ
ℓ2−8ℓ+12=0
Use quadratic formula (x=−b±√b2−4ac2a) to find ℓ
ℓ=−(−8)±√(−8)2−(4×1×12)2×1
ℓ=8±√162
ℓ=8±42
ℓ1=8+42=6
ℓ2=8−42
