Answer:
<h3>x = 83°</h3>
Step-by-step explanation:

Answer: GJ= 27.23
i dont know how to explain this lol sorry but that answer is right
Answer:
Step-by-step explanation:
|4x-3|=5√(x+4) ⇔ |4x-3|²=5²(√(x+4))² and x+4 ≥ 0
⇔ (4x-3)² = 25(x+4) and x+4 ≥ 0 ( because : /a/² = a²)
⇔16x²-24x+9 = 25x +100 and x+4 ≥ 0
⇔ 16x² -49x - 91 =0 and x+4 ≥ 0 quadratic equation
Δ = (-49)²-4(16)(-91) = 8225
two solution : X1 = (49-√8225)/32 ≅ - 1.3 accept (-1.3+4 ≥ 0)
X2 = (49+√8225)/32 ≅4.37 accept (4.37+4 ≥ 0)
We can simplify the expression by using exponent properties, and we will see that the correct option is the fourth option.
<h3>How to simplify the expression?</h3>
Remember the exponent property:

Here we have the expression:

We can reorder this to get:

The right side can be simplified to:

Now, we can move the decimal point one time to the left and increase the exponent by one, so we get:

Then we conclude that the correct option is the last one (where I rounded the expression to only 3 values after the decimal point).
