Answer:
x = 3x = - 5/3Step-by-step explanation:
2|3x - 2|= 14|3x - 2|= 71) 3x - 2 ≥ 0 ⇒ 3x ≥ 2 ⇒ x ≥ 2/3
3x - 2 = 73x = 9x = 3 is valid root as 3 ≥ 2/32) 3x - 2 < 0 ⇒ 3x < 2 ⇒ x < 2/3
- (3x - 2) = 73x - 2 = -73x = -5x = -5/3 is valid root as -5/3 < 2/3What is the positive square root of 81?
Answer:

f(x) = 4x – 10
g(x) = -8x2 + 6x – 10
Find: f(x) · g(x)
Answer: f(x) · g(x)=-32x³+104x²-100x+100
Step-by-step explanation:
Since we are given f(x) and g(x), all we have to do is multiply them together.
f(x) · g(x)=(4x-10)(-8x²+6x-10) [distribute by FOIL]
f(x) · g(x)=-32x³+24x²-40x+80x²-60x+100 [combine like terms]
f(x) · g(x)=-32x³+104x²-100x+100
Now, we have multiplied them together, we have f(x) · g(x)=-32x³+104x²-100x+100.
round 9.69 to the nearest whole number
Rounding 9.69 to the nearest whole number gives us 10.
Given that we need to round the decimal number 9.69 to the nearest whole number,
To round 9.69 to the nearest whole number, we look at the decimal part of the number, which is 0.69.
Since the decimal part is greater than or equal to 0.5, we round the whole number up to the next higher number. In this case, 9.69 is closer to 10 than to 9, so we round it up to 10.
Therefore, rounding 9.69 to the nearest whole number gives us 10.

Reginald has to put fertilizer on his yard. The bags of fertilizer cost $4.79 and cover 3500 square feet. Reginald's yard is a rectangle that measures 427 ft by 231 ft. How much will he spend on fertilizer?
He'll spend 138.91 dollars.
First multiply 427 and 231 to find out how much square feet you need to cover. Then divide the number by 3500 to see how many bags of fertilizer you need. Since there is a remainder, he'll have to buy another bag. Then, multiply the number of bags needed with the price of each bag to get the amount of money spent.
Use the FOIL method to find the product below.

Answer:
The slope is - 3Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
The equation is 3x+y = 4
To find the slope of the line we must first write the equation in the general form above
Make y the subject
That's
y = - 3x + 4
Comparing with the general equation above
Slope of the line = - 3

HELPPPPPPPP!!!!!!!
Answer:
x=1
Step-by-step explanation:
Use the distributive property on 2(4x - 4), which makes the equation 3x+8x-8=3
Simplify, which makes the equation 11x-8=3
Add 8 to both sides, which makes the equation 11x=11
Divide both sides by 11, which makes the equation x=1
There is a rectangular pool and small border. The pool and boarder measures x+3 by x-2. The pool alone measures x+2 by x+1. what is the area of the boarder
Answer:
-2x -8
Step-by-step explanation:
The border area will be the difference between pool+border and pool. The area of each rectangle is the product of its dimensions.
(x+3)(x-2) -(x+2)(x+1) = (x^2 +x -6) -(x^2 +3x +2)
= x^2(1 -1) +x(1 -3) +(-6 -2)
= -2x -8 . . . area of border

Question 23) Triangle PQR Triangle XYZ
PQ = 3a + 4 and XY = 5a - 12. Find a and PQ.
The value of 'a' will be 8.
And, The value of side PQ will be 28 units.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Triangle PQR ≅ Triangle XYZ
Now,
Since, Triangle PQR ≅ Triangle XYZ
So, we get;
Measure of PQ = Measure of XY
Substitute the given values of sides, we get;
Measure of PQ = Measure of XY
⇒ 3a + 4 = 5a - 12
Solve for a as;
⇒ 3a + 4 = 5a - 12
⇒ 3a - 5a = - 12 - 4
⇒ - 2a = - 16
⇒ 2a = 16
⇒ a = 8
Hence, Measure of PQ = 3a + 4
= 3 × 8 + 4
= 24 + 4
= 28
Thus, The value of 'a' will be 8.
And, The value of side PQ will be 28 units.
