Answer:
The answer would be 15.
Step-by-step explanation:
2x + 7 = x +4
2x = . x +1
x =11
2(11) =7
22-7
15.
Answer:
"first"
Step-by-step explanation:
The only variable is x, and this x is to the first power. So the degree of this poly is "first."
Answer:
4
Step-by-step explanation:
1 3/5 ÷ 2/5
Change the mixed number to an improper fraction
( 5*1+3)/5 ÷ 2/5
8/5 ÷ 2/5
Copy dot flip
8/5 * 5/2
Rewriting
8/2 * 5/5
4*1
4
Answer:
No, you should have learned this in 5th grade
Step-by-step explanation:
Trapezoid
x = 13.5 m - 7.5m / 2
= 6/2
= 3 m
Therefore x = 3 m
y = a^2=b^2 + c^2
= a^2 = 9^2 + 3^2
= a^2 = 90
= a = 9.5m
Therefore y = 9.5m
Perimeter = a+b+c+d
= 9.5 + 9.5 + 7.5 + 13.5
= 40m
Area= a+b/2 h
= 7.5+13.5/2 x 9
= 94.5 m^2
Kite
Area= p x q /2
= 12 x 9 /2
= 54 m^2
