Answer:
A) T = -1.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10t+4−2t=2−2(t+4)
10t+4+−2t=2+(−2)(t)+(−2)(4)(Distribute)
10t+4+−2t=2+−2t+−8
(10t+−2t)+(4)=(−2t)+(2+−8)(Combine Like Terms)
8t+4=−2t+−6
8t+4=−2t−6
Step 2: Add 2t to both sides.
8t+4+2t=−2t−6+2t
10t+4=−6
Step 3: Subtract 4 from both sides.
10t+4−4=−6−4
10t=−10
Step 4: Divide both sides by 10.
Hope this helps!

Answer:
The answer is: 83 + 12√35
(a + b)² = a² + 2ab + b²
In (2√5 + 3√7)², a = 2√5, b = 3√7
Just substitute a and b:
(a + b)² = a² + 2ab + b² = (2√5)² + 2 * 2√5 * 3√7 + (3√7)² =
= 2²√5² + 2 * 2 * 3 * √5 * √7 + 3²√7² =
= 4 * 5 + 12 * √(5*7) + 9 * 7 =
= 20 + 12 *√35 + 63 =
= 83 + 12√35
Step-by-step explanation:
We shall have to use distribution here.
The number outside the parenthesis gets distribute with the numbers inside.
This is called distributive property.
We know the distributive property is
a(b+c) = a × b + a ×c
Using this property for
5(4 x+2)
= 5× 4x + 5 × 2
Now 5 times 4x = 20x
5 times 2 = 10
So we get
5(4 x+2) = 20 x + 10
Option A) is the right answer.
