x= 0, -7

the reason that is true is because if you set each x equal to each other, you get x = 0 and x + 7 = 0 and if you subtract 7 on both sides you get x = -7

so x = -7, 0

Name:
Effectus [21]

Answer:

8421  

Step-by-step explanation:

8050 < abcd < 8500

We must have a = 8, so the number is 8bcd.

The value of a is 20 times the value of b, or a= 2b.

a = 8, so b = 4.

The value of b is 20 times the value of c, or b = 2c.

b = 4, so c = 2.

The value of c is 20 times the value of d, or c = 2d.

c = 2, so d = 1.

The secret number is 8421.

storchak [24]

Answer:

Surface area = 85.84 ft²

Step-by-step explanation:

Also, the two triangles area => 2(0.5 * base * height) = 2(4 x 3.46 x 0.5) = 13.84 ft²

Hence, the total surface area is

72 + 13.84 = 85.84 ft²

Therefore, the surface area of the fabric is 85.84ft²
