Answer:
A
B
C
Step-by-step explanation:
A
11=4(7)-17
11=28-17
11=11
B
-13=4(1)-17
-13=4-17
-13=-13
C
-1=4(4)-17
-1=16-17
-1=-1
Area of rectangle is the multiplication between the sides.
The first rectangle:
A = (2x + 5) . (3x - 2)
A = 2x . 3x - 2 . 2x + 5 . 3x - 2 . 5
A = 6x² - 4x + 15x - 10
A = 6x² + 11x - 10
The second rectangle:
A = (5y + 5) . (2y - 3)
A = 5y . 2y - 3 . 5y + 5 . 2y - 3 . 5
A = 10y² - 15y + 10y - 15
A = 10y² - 5y - 15
Answer:30
Step-by-step explanation:
The answer is $412.
Let's first calculate simple interest. Simple interest (I) can be expressed as:
I = P * r * t
P - principal
r - rate
t - time period
It is given:
I = ?
P = $400
r = 3% = 0.03
t = 1 year
Therefore:
I = P * r * t = 400 * 0.03 * 1 = 12
The total amount Kate will repay is the principal amount (P) plus 3% simple interest (I):
P + I = 400 + 12 = $412
Answer:
136 ft^2
Step-by-step explanation:
Surface area = 2 [ (l*w) + (l*h) + (w*h) ]
= 2 [ (8*3) + (8*4) + (4*3) ]
= 136 ft^2
