Answer:
512
Step-by-step explanation:
when q = 2, w = 3
4q(q + 3w)^2
= 4(2) ((2)+3(3))^2
= 512
Answer:
<ABC = 49°
Step-by-step explanation:
The sum of two supplementary angle is 180. From the diagram, the two angles are 3x+4 and 8x+11. IF this two angles are supplementary then;
3x+4+8x+11 = 180
11x+15= 180
11x = 180-15
11x = 165
x = 165/11
x = 15
From the attached diagram, <ABC = 3x+4
<ABC = 3(15)+4
<ABC = 45+4
<ABC = 49°
Answer:
60 songs.
Step-by-step explanation:
The percentages there are an equal sign so
0.45x=27
x=60
So Brianna listened to 60 songs!
Simplifies the problem, you divide by a value which if plugged into x would equal 0. One example is dividing by (x-1) as x=1 results in 0
Answer:
Length = 64 cm , width =16 cm
Step-by-step explanation:
Given Perimeter = 160
Let width = x
Length = 4x
Hence perimeter =2 (length) +2 ( width)
160 = 2(4x)+2(x)
160 = 8x + 2x
160 = 10x
160/10 =x
16 = x
Hence width = 16 cm
Put the value of x in 4x
Length= 4(16)
Length =64 cm
Hence length = 64 cm, width =16 cm
