34. The sum of the lengths of the two bases of a trapezoid
Oduvanchick [21]

Answer:

h=6

Step-by-step explanation:

the formula for a trapezoid’s area is to multiply the bases (a and b) by the height of the trapezoid, then divide it all by 2.

so typed out, that would look like:

((a+b) h) / 2

and in the case of this problem:

((22) h) / 2 = 66

so just go ahead and solve it algebraically from there and you’re good!

a couch sells for $1260. instead of paying the toatl amount at the time of the purchase, the same couch can be brought by paying
bixtya [17]
If you pay $400 down, plus $80 for the next 12 months, that means you're paying (80*12)+400 which is equal to $1360. You're saving $100 by paying the entire total up front.

Wrie down the equation of the line that is parallel to 4x - 2y = 7 and passes through (9, -3) ​
EastWind [94]

Answer:

4x-2y =42 is the required equation

Step-by-step explanation:

given equation is,

4x-2y -7=0---------eqn1

parallel equation of given equation is

4x -2y+k =0-------eqn 2

now passing it through (9,-3), we get,

4×9 + 2×3 +k = 0

or,36+6+k =0

or,42+k =0

or, k= -42

putting the value of k in eqn2

4x-2y - 42=0

4x-2y = 42
