You have to take the x to on side and numbers to the other but in order to do that you'll have to divide -3 from both sides and then just solve the equation.
First, distribute 8 to both k and -4, and 8k to both 7k and 8
8(k - 4) = 8k - 32
8k(7k + 8) = 56k² + 64k
Combine like terms
56k² + (64k + 8k) - 32
56k² + 72k - 32
56k² + 72k - 32 is your answer
hope this helps
Can’t see the picture clearly
A=l√[(w/2)²+h²+w]+w√[(l/2)²+h²]
where
l is base length
w base width
h is height
given that the slant side of our pyramid is 856.1 ft with square base of 145 ft, the height of the pyramid will be found by Pythagorean theorem.
c²=a²+b²
hence:
856.1²=a²+72.5²
a=853.025 ft
The Lateral area is therefore going to be:
A=145√[(145/2)²+856.025²+145]+145√[(145/2)²+856.025²]
A=249,136.0025 ft²
Answer:
791.2 ft
Step-by-step explanation:
The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.
where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then
