2(x + 4) = -5x + 1
2x + 8 = -5x + 1
2x + 5x = 1 - 8 = -7
7x = -7
x = -7/7 = -1
x = -1

tino4ka555 [31]
To solve the problem we use the compound formula given by:
A=p(1+r/100)^n
where:
A=future amount:
p=principle
r=rate
A=1000000, r=11.6%, n=40
plugging the value in the formula we get:
1000000=p(1+11.6/100)^40
solving for p we get:
1000000=80.6432p
p=12400.300
rounding to the nearest 1000 we get
p=$12000

IrinaK [193]

Answer:

143 cm²

Step-by-step explanation:

There are 3 pairs of sides to this shape,

1 pair is the top and bottom pieces, each has an area of 4(3) = 12 cm², so there are 24 cm² from this pair.

the second pair is the front and back pieces, each has an area of

4(8.5) = 34 cm², so there are 68 cm² from this pair.

the third pair are the side pieces, each has an area of

3(8.5) = 25.5 cm², so there are 51 cm² from this pair.

Al together there are 24 + 68 + 51 = 143 cm²
