Answer:
t = 2
Step-by-step explanation:
5(6t-3)=5t+35
Step 1 distribute the 5 by multiplying 5 to what is inside of the parenthesis
5(6t) - 5(3) = 5t + 35
Outcome: 30t - 15 = 5t + 35
Step 2 add 15 to both sides
30t - 15 + 15 = 5t + 35 + 15
Outcome: 30t = 5t + 50
Step 3 subtract 5t from both sides
30t - 5t = 5t - 5t + 50
Outcome: 25t = 50
Step 4 divide both sides by 25
25t/25 = 50 we're left with t = 2

Answer:
The "3y" in the first term is a factor
The "9" in the second term is a coefficient
The "(7 + 2x)" in the first term is a factor
Step-by-step explanation:
Given in the question an expression
3y(7 + 2x) + 9xy - 10
- The coefficients are the numbers that multiply the variables, x and y.
<h3>Example</h3>
6y
6 is coefficient
2.Constants are terms without variables
<h3>Example</h3>
10
3.The factors in a mathematical expression are parts of the expression that are connected with multiplication.
<h3> Example</h3>
(4x+1)(3x+7)
(4x+1) and (3x+7) both are factors
Answer:
x = √2 = 1.414
Step-by-step explanation:
5x-(x+2)^2=x^2-8+x
since (x+2)^2 = x^2 + 2(x)(2) + 2^2 = x^2 + 4x + 4
so
5x - (x^2 + 4x + 4) = x^2 + x - 8
-x^2 + x - 4 = x^2 + x - 8
x^2 + x^2 + x - x = -4 + 8
2x^2 = 4
x^2 = 2
x = √2 = 1.414
