45.3 x 2.34<br> 3.7 x 0.26<br> 0.4 x 0.9<br> 12.98 x 13<br> 0.05 x 1.2
Sedbober [7]

Answer:

I don't know exactly what you're looking for so here

45.3 x 2.34 = 106.002

3.7 x 0.26 = 0.962

0.4 x 0.9 = 0.36

12.98 x 13 = 168.74

0.05 x 1.2 = 0.06

45.3 x 2.34 x 3.7 x 0.26 x 0.4 x 0.9 x 12.98 x 13 x 0.05 x 1.2 = 371.672926612

nirvana33 [79]

Answer:

The base is x^4 -2x^3 -3x-1

Step-by-step explanation:

We know the perimeter of a triangle is the sum of the three sides

P = s1+s2+s3

We know the perimeter is  5 x^4 − 2 x^3 + x − 3

and two of the legs are 2 x^4 + 2 x − 1  since it is an isosceles triangle

P = 2s1 + s3

Subtract 2s1 from each side

P-2s1 =2s1 +s3 -2S1

P -2s1 =s3

Substituting what we know

5 x^4 − 2 x^3 + x − 3 - 2(2 x^4 + 2 x − 1) = s3

Distribute the -2

5 x^4 − 2 x^3 + x − 3 - 4 x^4 -4 x + 2 = s3

Combine like terms

5 x^4-4x^4 − 2 x^3 + x  -4 x -3+ 2 = s3

x^4 -2x^3 -3x-1 =s3

The base is x^4 -2x^3 -3x-1
