Answer:
A = 66.5 in²
Step-by-step explanation:
There are a few different equations to find the area of a rhombus. If you are given the measurements of the two diagonals, you can use the following formula:
Area (A) = 
Using this formula, you can multiply the measures of the diagonals and then divide by 2:
area = 
Answer:
(8) x+8 in (8)
Step-by-step explanation:
width times length
Answer:
x = - 4, x = 9
Step-by-step explanation:
Given
x² - 36 = 5x ( subtract 5x from both sides )
x² - 5x - 36 = 0 ← in standard form
(x - 9)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 9 = 0 ⇒ x = 9
x + 4 = 0 ⇒ x = - 4
You have to square it all up then add it up if you want you can use the calculator
Number 7 is A and number 8 is C, i’ve had this before
