Answer:
w=3 (please give me brianliestt!!)
Step-by-step explanation:
4w+3=3w+6 (subtract 3 from both sides)
-3 -3
4w=3w+3 (subtract 3w on both sides)
-3w -3w
1w=3 (divide by 1)
w=3
Answer:
The area of the square is increasing at a rate of 40 square centimeters per second.
Step-by-step explanation:
The area of the square (), in square centimeters, is represented by the following function:
(1)
Where is the side length, in centimeters.
Then, we derive (1) in time to calculate the rate of change of the area of the square (), in square centimeters per second:
(2)
Where is the rate of change of the side length, in centimeters per second.
If we know that and , then the rate of change of the area of the square is:
The area of the square is increasing at a rate of 40 square centimeters per second.
Answer:
Step-by-step explanation:
Given: 4 - 9x +21
Factorizing this expression, we have;
4 -3(3x - 7)
i. Chang's expression: 4 - 3(3x + 7)
This is not an equivalent expression, because by expansion of the bracket, the expression gives: 4 -9x -21
ii. Benjamin's expression: 4 + 3(3x + 7)
This is not an equivalent expression, because by expansion of the bracket, the expression gives: 4 +9x +21
iii. Habib's expression: 4 + 12x
This is not an equivalent expression, because the expression is not related to the given question
Comparing the three student's answers with the appropriate expression, none of the student's is an equivalent expression.
This expression that is equivalent to the given question is;
4 -3(3x - 7) = 4 -9x + 21
Answer:
1,2,4
Step-by-step explanation:
The rectangular coordinates of polar vector (r, θ) are (r·cos(θ), r·sin(θ)). For your (r, θ) = (8.8, 170°), the rectangular coordinates are
... (8.8·cos(170°), 8.8·sin(170°)) ≈ (-8.666, 1.528)

Hope I helped
Do u want the steps ?
Answer: x > -3
Step-by-step explanation: -5(4x + 7) <25
-20x - 35 < 25
-20x -35 + 35 < 25 + 35
-20x/20 < 60/20
x > -3
