Answer:
56 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(a + b)
where h is the perpendicular height and a, b the parallel bases
here h = 4, a = 5 + 9 + 5 = 19 and b = 9, thus
A = × 4 × (19 + 9) = 2 × 28 = 56 cm²
Answer: y= 4
Step-by-step explanation:
16y-12= 53 add 12 on each side
16y= 65
Divide by 16
4.0625
Answer:
1 and 2
Step-by-step explanation:
let the consecutive integers be n and n + 1 , then
6n = 3(n + 1)
6n = 3n + 3 ( subtract 3n from both sides )
3n = 3 ( divide both sides by 3 )
n = 1
and n + 1 = 1 + 1 = 2
The integers are 1 and 2
Answer:
Yes give Brainliest
Step-by-step explanation:
To find y place the other terms in the equation to the right
hand side of the equation.
Thus : 5y = 7 - 3x
( now divide both sides by 5 )
⇒ 5y5=7−3x5=15(7−3x)
now will you give brainliest?
