Answer:
d=7
Step-by-step explanation:
To find d youll have to find it. 9d + 4 = 2d + 53 minus 2d on both sides> 7d+4=53 now minus 4 on both sides> 7d=49 divide 49/7 > d=7

Answer:
Frequency
Step-by-step explanation:
"A dot plot is a visual display in which each piece of data is represented by a dot above a number line, showing the frequency of each data value. The total number of dots in the plot is the total number of values in the data set. The data points must all be in the same units."
<span>x(x−3)=54
x^2 - 3x - 54 = 0
(x - 9)(x +6) = 0
x - 9 = 0 so x= 9
x + 6 = 0 so x = -6
</span><span>
x = 9 (length)
so width = x - 3 = 9 -3 = 6
</span>answer
<span>length = 9
double check
Area = LxW = 9x6 = 54

Answer:
Perimeter = 54.6 cm
Area = 173 cm²
Step-by-step explanation:
sin 30 = x/20
x = 10
cos 30 = y /20
y = 17.3
perimeter = 10 + 17.3 + 10 + 17.3 = 54.6 cm
area = 10 * 17.3 = 173 cm²
