Answer:
a. Yes
b. 3x+7
c. 105 cm
Step-by-step explanation:
a. a(1)+b=10
a(2)+b=13
when you solve this by elimination or simultaneously: a=3 and b=7
∴ f(x)=3x+7
b. f(x)=3x+7
c. 3(35)+7=112 cm
Answer:
Cube 2
Step-by-step explanation:
The order of operations are PEMDAS.
P = parenthesis
E = exponent
M = multiplication
D = division
A = addition
S = subtraction
Since we don't have any parenthesis, so the first thing we have to do is solve the exponent
The answer would be x + x + 2 = 72. Combine like terms so that 2x + 2 = 72. 2x = 70 and x = 35.
