Answer:
A = 70 units²
Step-by-step explanation:
Since all 4 sides are congruent then figure is a rhombus
The area (A) of a rhombus is calculated as
A = × d₁ × d₂ ( d₁ and d₂ are the diagonals )
Here d₁ = 7 + 7 = 14 and d₂ = 5 + 5 = 10 , then
A = × 14 × 10 = 7 × 10 = 70 units²
It factors out to: (a-5b)(a+9b)
Answer:
$12.75
Step-by-step explanation:
To find the unit price of something divide the cost by the amount of the Item
Answer:
Step-by-step explanation:
1st side X-17
2nd side X
3rd side X-6
(X-17)+(X)+(X-6) = 49
-17-6 = -23
X+X+X-23 = 49
3X-23 = 49
3X-23+23 = 49 + 23
3X = 72
3x/3 = 72/3
x = 24
Now plug it in
(24-17)+24+(24-6) = 49
7+24+18 = 49
Answer:
(x + 7) (x + 5)
Step-by-step explanation:
Factor the following:
x^2 + 12 x + 35
The factors of 35 that sum to 12 are 7 and 5. So, x^2 + 12 x + 35 = (x + 7) (x + 5):
Answer: (x + 7) (x + 5)
