The approximate value of x will be approximately equal to 3.4
<h3>Area of triangle and circle</h3>
The formula for calculating area of rectangle is expressed as:
A = lw
- l is the length
- w is the width
Ar = (3x-1)(x+2)
Ar = 3x^2+6x-x-2
Ar = 3x^2 + 5x - 2
For the circle
Ac = πr²
Ac = 3.14(x-3)²
Ac = 3.14(x²-6x+9)
Ac = 3.14x² - 18.84x + 28.26
If the area are equal;
3x² + 5x - 2 = 3.14x² - 18.84x + 28.26
3.14x² - 3x² - 5x - 18.84x + 30.26 = 0
0.14x²-23.84x+30.26 = 0
On factorizing the equation, the approximate value of x will be approximately equal to 3.4

I’m assuming you mean -1/4 -4, and since you’re subtracting a negative by a negative, it would be -4 1/4(mixed number)
Answer: the answer is A
Step-by-step explanation: 400 times 2.5 is 1000 and 250 times 2.5 is 625 and together they equal 1625
Answer:
25,000 grams
Step-by-step explanation:
Density can be found using the following formula:
If we rearrange the formula for 
, mass, we will multiply both sides of the equation by v.
The mass can be found by multiplying the density by the volume.
Jeff's density is 1000 grams per milliliter and his volume is 25 milliliters.
Substitute the values into the formula.
Multiply. When you multiply, the "mL" or milliliters will cancel out.
Jeff's mass is 25,000 grams.
