Add 12 to 16 on the other side to make 4x = 28. Then divide 28 by 4, which equals 7. Solution is x = 7
The first answer is 2
The Second is 8
The third is, if the w changes then the p would change as well resulting to multiplication
Hope this helps!!!
<span>Let the width of the rectangular plot of land be 'x' yards.
Given that the length of the rectangular plot of land is 10 yards more than its width.
So, width of the rectangular plot of land = (x + 10) yards.
Also given that the area of the rectangular plot of land is 600 square yards.
We know that, area of a rectangle = length * width
That is, (x+10) * x = 600
x^2 + 10x = 600
x^2 + 10x - 600 = 0
x^2 + 30x - 20x -600 = 0
x(x + 30) - 20(x + 30) = 0
(x +30)(x -20) =0
Therefore, either (x + 30) = 0 or (x - 20) = 0
If x + 30 = 0, then x = -30 and
If x - 20 = 0, then x = 20
Since 'x' represents the width of a rectangular plot of land it cannot be negative.
Therefore,
width of the rectangular plot of land = 20 yards
length of the rectangular plot of land= x + 10 = 30 yards</span>
Answer:
4. 11/6, 121/36
5. 5/8, 25/64
6. 4/7, 16/49
7. 14/9, 196/81
Step-by-step explanation:
The ratio of perimeters is the same as the ratio of corresponding legs:
perimeter ratio = red leg/blue leg
The area ratio is the square of that:
area ratio = (perimeter ratio)²
__
<h3>4.</h3>
perimeter ratio = 11/6
area ratio = (11/6)² = 121/36
__
<h3>5.</h3>
perimeter ratio = 5/8
area ratio = (5/8)² = 25/64
__
<h3>6.</h3>
perimeter ratio = 4/7
area ratio = (4/7)² = 16/49
__
<h3>7.</h3>
perimeter ratio = 14/9
area ratio = (14/9)² = 196/81
The answer is 142°
Explanation:
angle 1 and angle 2 form are supplementary.
m∠1 + m∠2 = 180°
38° + m∠2 = 180°
m∠2 = 180° - 38°
m∠2 = 142°
Hope it helps!
