Answer:

Hence the required dimension is 4cm.

Step-by-step explanation:

Given:

An Isosceles triangle with uneven side=l+1 cm

Area= 6 sq cm

To Find:

Height of Triangle.

Solution:

We know that area of triangle given by,

Area=1/2*base*height.

Here height =1+base

6=1/2((b+1)*b

12=(b+1)*b.

b^2+b-12=0

(b-3)(b+4)=0

b=3 or b=-4

So length never be negative

so b=3 cm

And height=b+1=3+1=4 cm.

kramer

Combine like terms:

-12 + 5a - a - 6a + 8a + 8 + 3a

-12 + 5a - a - 6a + 8a + 8 + 3a

5a - a = 4a

4a - 6a = -2a

-2a + 8a = 6a

6a + 3a = 9a

-12 + 8 = -4

Answer

9a - 4

Sam paid $8.28 for 18 stamps.at this rate,how much would it cost Sam to buy 12 stamps
allsm [11]

Answer: It costs $5.52 to Sam to buy 12 stamps.


Step-by-step explanation:

Given: Sam paid $8.28 for 18 stamps.

Thus, the cost of 18 stamps = $8.28

Then the cost of 1 stamp=\frac{8.28}{18}

Thus, the cost of 1 stamp=$0.46

With the same rate , the cost of 12 stamps=0.46\times12

Therefore, the cost of 12 stamps= $5.52

hence, it costs $5.52 to Sam to buy 12 stamps.
