A) The dimensions are (x+10) by (x+10).
B) The perimeter is given by 4x+40.
C) The perimeter when x is 4 is 56.
The quadratic can be factored by finding factors of c, the constant, that sum to b, the coefficient of x. Our c is 100 and our b is 20; we want factors of 100 that sum to 20. 10*10=100 and 10+10=20, so those are what we need. This gives us (x+10)(x+10 for the factored form.
Since the dimensions are all (x+10), and there are 4 sides, the perimeter is given by 4(x+10). Using the distributive property we have 4*x+4*10=4x+40.
To find the perimeter when x=4, substitute 4 into our perimeter expression:
4*4+40=16+40=56.
Answer:
A) The dimensions are (x+10) by (x+10).
B) The perimeter is given by 4x+40.
C) The perimeter when x is 4 is 56.

O x=-14
Please help
Will give you brainly
Answer:
x = -6
Step-by-step explanation:
We have the equation 3x - 4 = 2x - 10 and are asked to find "x".
To solve , we need to get "x" alone entirely.
3x - 4 = 2x - 10
Subtract 2x from both sides :
x - 4 = -10
Add 4 to both sides to get our answer :
x = -6

the answer is equal to-6

Solve the system 8y-5z=23 3y-2z=6
100 POINTS
Answer:
z = 21 ; y= 16
Step-by-step explanation:
first of all we have to isolate a variable.
In second expression we can obtain:
3y = 2z+6
y = 2/3 z + 2
now we have to substitute this value in the first equation and solve it
8(2/3z+2)-5z = 23
16/3z + 16 -5z = 23
16z +48 - 15z = 69
z = 21
now we have to substitute z in the second equation:
y = 2/3 (21) +2
y = 14+ 2 = 16
y = 16

Stephanie earns $750 a month. she gives
30% of the money to charity. How much money
does Stephanie give charity?
Answer:
she gives 225
Step-by-step explanation:
750×30% equals to 225
Answer:
Stephanie gives $225 to charity a month
Step-by-step explanation:
$750 / 100 = 7.5
7.5 x 30 = 225
7.5 x 70 = 525
700 - 525 = 225
What is the distance between the points (-6, 2) and (-4, 7)? Round to the nearest tenth if necessary.
Answer: distance is 5.4
Step-by-step explanation: distance between points (X1,y1) and (x2,y2) is
√(x2-X1)² + (y2-y1)² = √[(-4-(-6))² + (7-2)²] = √(2²+ 5²) =√29
The distance between the points (-6, 2) and (-4, 7) is 5.4 units.
What is the distance formula?The distance between any two points (x₁, y₁) and (x₂, y₂) can be determined using the distance formula according to which,
Distance = √((x₂ - x₁)² + (y₂ - y₁)²).
How do we solve the given question?We are asked to find the distance between the points (-6, 2) and (-4, 7).
We will determine the distance using the distance formula, by which
Distance = √((x₂ - x₁)² + (y₂ - y₁)²)
or, Distance = √(((-4) - (-6))² + (7 - 2)²)
or, Distance = √((-4 + 6)² + (7 - 2)²) = √(2² + 5²) = √(4 + 25) = √29
∴ Distance = √29 = 5.385165 = 5.4 (rounding to the nearest tenth).
∴ The distance between the points (-6, 2) and (-4, 7) is 5.4 units.

The graph shows one of the linear equations for a system of equations. Which equation represents the second linear equation for the system of equations that has the solution which corresponds to a point at (6, -2)?
A. 1/3x + 3y = 4
B. 1/3x + 4y = -4
C. 1/3x + 2y = -2
D. 1/3x + 2y = 2
Answer:
C. 1/3x + 2y = -2
Step-by-step explanation:
Using the point slope form of an equation
y-y0 = m(x-x0)
Get the slope m
Get the x and y intercept of the equation
Using the expression 1/3x + 2y = -2
x intercept occurs at y = 0
1/3x + 0 = 2
1/3 x = 2
x = 3 * 2
x = 6
y intercept occurs at x = 0
0+ 2y = 2
2y = -2
y = -1
Hence the required equation is C. 1/3x + 2y = -2

A rectangle and a square have the same area. a. The width of the rectangle is w inches. The length of the rectangle is 15 inches less than 4 times the width of the rectangle. Write a polynomial to represent the area of the rectangle. b. The side of the square is w inches. Write a polynomial to represent the area of the square. c. Write an equation such that the area of the rectangle is equal to the area of the square. d. Solve the equation in part (c) to find the side length of the square. e. What are the length and the width of the rectangle?
9514 1404 393
Answer:
a) w(4w-15)
b) w²
c) w(4w -15) = w²
d) w = 5
e) 5 by 5
Step-by-step explanation:
a) If w is the width, and the length is 15 less than 4 times the width, then the length is 4w-15. The area is the product of length and width.
A = w(4w -15)
__
b) If w is the side length, the area of the square is (also) the product of length and width:
A = w²
__
c) Equating the expressions for area, we have ...
w(4w -15) = w²
__
d) we can subtract the right side to get ...
4w² -15w -w² = 0
3w(w -5) = 0
This has solutions w=0 and w=5. Only the positive solution is sensible in this problem.
The side length of the square is 5 units.
__
e) The rectangle is 5 units wide, and 4(5)-15 = 5 units long.
The rectangle and square have the same width and the same area, so the rectangle must be a square.
