Answer:
Step-by-step explanation:
we have
Applying distributive property
Remember the properties
so
Combine like terms
The leading coefficient is the coefficient of the highest power in this case x^2 (x squared)
x^2 has no number written before it , so it's 1 (last choice)
Answer:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
a-(9*x^2-6*x+1)=0
STEP
1
:
Equation at the end of step 1
a - ((32x2 - 6x) + 1) = 0
STEP
2
:
Equation at the end of step 2
a - 9x2 + 6x - 1 = 0
STEP
3
:
Solving a Single Variable Equation:
3.1 Solve a-9x2+6x-1 = 0
39-23= 16. Mary ran 16 miles
Answer:
B
Step-by-step explanation:
surface area is finding the area of each portion of the net and adding them all up together. all the triangles are congruent, so we can start by finding the area of one of them and multiplying that area by 4 (since there are 4 triangles in this net). the formula for the area of a triangle is 1/2 bh. this is (1/2)(5.95)(5.1) which equals approximately 15.17. 4 multiplied by this is 60.68. the area of the square is length multiplied by width, which is 26.01. 60.68+26.01=86.69, which is the closest to answer choice B.
