Answer:
Required number is 4.
Step-by-step explanation:
Let the required number be a.
Given,
Sum of ten times the integer and seven times it’s square is 152.
= > Ten times of a + seven times of it's square = 152
= > 10( a ) + 7( a )^2 = 152
= > 10a + 7a^2 - 152 = 0
= > 7a^2 + 10a - 152 = 0
= > 7a^2 + ( 38 - 28 )a - 152 = 0
= > 7a^2 + 38a - 28a - 152 = 0
= > a( 7a + 38 ) - 4( 7a + 38 ) = 0
= > ( a - 4 )( 7a + 38 ) = 0
= > a = 4 or - 38 / 7
Hence the required number is 4.

Step-by-step explanation:
Answer:
A possible measure of Line segment TS is 4.0 ft
Step-by-step explanation:
<u><em>The options of the question are</em></u>
1.6 ft 3.0 ft 3.2 ft 4.0 ft
we know that
In any triangle:
The shortest side is always opposite the smallest interior angle.
The longest side is always opposite the largest interior angle
In this problem

That means

Rewrite the expression

so

therefore
A possible measure of Line segment TS is 4.0 ft
