Answer:
A =42 in^2
Step-by-step explanation:
This is a trapezoid
The area of a trapezoid is found by
A = 1/2(b1+b2)h where b1 and b2 are the lengths of the bases
A = 1/2(13+8) *4
A =42 in^2
Answer:
6; 22; 20 (ft.)
Step-by-step explanation:
1) if the length of the each side are: n; 4n-2 and 4n-4, then the expression of the perimeter can be written: P=n+4n-2+4n-4 or P=9n-6.
2) if according to the condition perimeter is 48 (ft.), then
9n-6=P; ⇔ 9n-6=48; n=6.
3) if n=6, then the required lengths of the sides are:
n=6 (ft.);
4n-2=22 (ft.);
4n-4=20 (ft.)
Answer:
9
Step-by-step explanation:
3y-(4y+6x)
=3*3-(4*3+6*-2)
=9
An addition sentence is just addition.
1 3/4 + 1 1/3 + 1 3/4 = ?
7/4 + 7/4 + 4/3
First find the lowest common denominator.
21/12 + 21/12 + 16/12
= 58/12 = 4 10/12 = 4 5/6
