Answer:
2+5*3=17
Step-by-step explanation:
The blanks should be filled in with a plus (+) and a times sign (*), respectively. To solve this question you must understand PEMDAS. This stands for paratheses, exponents, multiplication, division, addition, subtraction. When solving an equation, operations should be done in this order. Therefore, numbers should be multiplied before they are added.
So, to solve this equation multiply 5*3; this equals 15. Then add 2, which equals 17. And 17=17, so the equation must be true.
Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
x2+4=3x+8
Step 1: Subtract 3x+8 from both sides.
x2+4−(3x+8)=3x+8−(3x+8)
x2−3x−4=0
Step 2: Factor left side of equation.
(x+1)(x−4)=0
Step 3: Set factors equal to 0.
x+1=0 or x−4=0
x=−1 or x=4
Answer:
x=−1 or x=4
