Given :
When 7 is subtracted from five times a number, the result is greater than twice the sum of the number and 4.
To Find :
All the numbers that satisfy the inequality.
Solution :
Let , the number is x .
Mathematical expression for first term is :
5x - 7
Mathematical expression for second term is :
2(x + 4)
Now , comparing both the expression by given constrain.
So, all the numbers that satisfy the inequality are greater than 5.
Hence , this is the required solution.
Answer:
2x + 14
Step-by-step explanation:
To evaluate h(x + 5) substitute x = x + 5 into h(x), that is
h(x + 5) = 2(x + 5) + 4 = 2x + 10 + 4 = 2x + 14
Answer:
329.91 cm^2
Step-by-step explanation:
A ring-shaped region is shown below. Its inner radius is 8m, and its outer radius is 11m. 8m 11m Find the area of the shaded region. Use 3.14 for π. Do not round your answer.
Your answer
Given data
inner radius= 8cm
area= πr^2
area= 3.142*8^2
area= 3.142*16
area= 50.272 cm^2
outer radius= 11cm
area= πr^2
area= 3.142*11^2
area= 3.142*121
area= 380.182 cm^2
Hence the area of the shaded part is
=380.182-50.272
=329.91 cm^2
X must =2 9x2 =18+3=21 they are equal
