Answer:
Volume = 42 units^2
x = 5 units
Total Surface Area = 96 units
Step-by-step explanation:
Volume
V = bh, where b = 1/2 * 3 * 4 and h = 7,
= 6 * 7 = 42 units^2
x
You can solve for this variable by using the pythagorean theorem;
a^2 + b^2 = c^2, where a = 3 and b = 4,
9 + 16 = x^2
= 25 = x^2
= x = 5 units
Total Surface Area
You can solve this by multiplying the perimeter of the base (3 + 4 + 5) by the height and adding that to two times the area of the base:
7 * (3 + 4 + 5) + 2(1/2*3*4)
= 7*12 + 12
= 96 units
−(x^2−6x+7) that is the answer
First convert them to fractions (the answer choices are fractions):
a) 0.333... = 1/3
b) 0.555... = 5/9
Now add a and b:
1/3 (or 3/9 for a common denominator) + 5/9 = 8/9
That fraction is in simplest form, so leave it as it is.
Hope this helps!
