Value of y = 30
Step-by-step explanation:
We are given the following equations in the question:
We have to solve the given equation for y and z.
Equating the two equations we get,
Value of z = 7
Value of y = 30
Answer
Acute angle

Answer:
good news, the second one is relatively easy because it can be factored to (2x+1)(2x-3) which means that number two has solutions of -1/2 and 3/2
but for number one you have to either use the quadratic equation cause I've tried using synthetic division or just use the second equation to derive the first solutions so I tried move the graph up by two units and found that the intercepts are approximately (1+-√2)/2 or 1/2+-1/√2 for 4x^2-4x-1
Split the second term in 4x^2 + 17x - 15 into two terms
4x^2 + 20x - 3x - 15
Factor out the common terms in the first two terms, then in the last two terms.
4x(x + 5) -3(x + 5)
Factor out the common term x + 5
<u>(x + 5)(4x - 3)</u>
For the volume of this solid, you’re first going to find the area of the front triangle. so base x height divided by 2. for this it would just be 4.5. then multiply that by the side length. so 4.5 x 3.5, which would be 15.75. so your answer would be 15.75 cubic centimeters
