11 in - 7 in = 4 in
a^2 + (4 in)^2 = (5 in)^2
a^2 + 16 in = 25 in
a^2 = 9 in
a = 3 in
7 in x 3 in = 21 in
1/2( 3 in ) ( 4 in ) = 6 in
a = 21 in + 6 in = 27 in
Answer:
14.39
Step-by-step explanation:
Answer:
Step-by-step explanation:
the end behavior refers to what happens when x approaches negative infinity and infinity
as x approaches negative infinity (to the left), the values are all negative inside the parentheses so multiplying -∞ * -∞ * -∞, you get g(x) approaches -∞ as x approaches -∞
as x approaches ∞(to the right), the values inside the parentheses are all positive ∞ so multiplying ∞*∞*∞, you get g(x) approaches ∞ as x approaches ∞
Answer:
30 years
Step-by-step explanation:
Let :
Spike's age = x
Rex age = 6x
Rex mother = 10 * 6x = 60x
Rex father = 2 * 60x = 120x
x + 6x + 60x + 120x = 1000
187x = 1000
x = 1000/ 187
x = 5.34
Hence, Spike's age, x = 5 years
Rex age = 5 * 6 = 30 years
Answer:
B
Step-by-step explanation:
Let's call the shortest side a. The longest base, b, is 8cm longer than a. The height, h, is 2cm longer than a.
b = a + 8
h = a + 2
A = (a + b)h/2
48 = (a + (a+8))(a+2)/2
= (2a+8)(a+2)/2
= (2a^2+12a+16)/2
48 = a^2+6a+8
a^2+6a-40=0
Now, we factor this:
(a + 4)(a - 10)=0
a = -4, 10
a (length) cannot be a negative no. so the only possible answer is a = 10.
b = 10 + 8 = 18
h = 10 + 2 = 12
The answer is B
Hope this helps!
