4(5) - 2/-2(-3) + 1
20 - 2/6 + 1
18/7
2 4/7
Letter b
Answer:
Step-by-step explanation:
Using perimeter =2(l+b)
74=2(L+B)
From the question
Width(b)=x & length(l)=3x+5
So we have that
74 =2(3x+5+x)
Adding like terms we then have that
74 =2(4x+5)
Opening the bracket gives
74=8x +10
Collecting like terms
8x=74-10
8x= 64
Therefore
X=64/8
X=8feets
The width is 8feets
Answer:
slope=0, equation: y=2
Step-by-step explanation:
Diagonal PQ is a horizontal line so it's slope is zero.
Since it is a horizontal line, its equation is just the y-intercept (0 slope), which in this case is y=2.
Area of kite is 1/2 times the two diagonals.
So, it would be 1/2 times 70 times 70.
Solve it and you get 2450.
The answer is 2450 square cm.
But the question is asking for meters so convert it.
1 cm is 0.01 in meters. 2450 times 0.01 equals 24.5 meters
24.5 square meters is your final answer.
Answer:
5
Step-by-step explanation:
2x + 15 = 3x + 10
3x + 10 = 2x + 15
3x - 2x = 15 - 10
x = 5
