Welcome to Brainly, Dolly!

49 factors into 7^2. 7 is prime, and 49 is the square of this prime factor.

56 = 7(8), but 8 itself is the cube of 2. Thus, 56 = 7*2^3: 7*2*2*2.

42 = 7(6) = 7*2*3

Find the output, kkk, when the input, ttt, is -7−7minus, 7.<br> k = 10t-19k=10t−19

Sati [7]

The output k at input t = -7 is -89

Step-by-step explanation:

In order to find the value of a expression on given number, we put the number in given expression in place of independent variable

So,

Given expression is:

$k = 10t-19$

It is given that the value of t has to be -7

so putting t=-7 in the expression

$k = 10(-7)-19\\k = -70-19\\k = -89$

Hence,

The output k at input t = -7 is -89
