Answer:
Step-by-step explanation:
x+4=2x-3
x-3=4
x=7
Answer:
x = -4, x = 6
Step-by-step explanation:
to find the zeros, set f(x) = 0, hence
x² - 2x - 24 = 0 ( factoring the quadratic )
(x - 6)(x + 4) = 0
equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 6 = 0 ⇒ x = 6
Answer:
56.714°
Step-by-step explanation:
Since we do not have a full angle of this proposed triangle, we must do this by splitting it into two right triangles instead of using the law of sines.
250m*sin(40°) = 250m*0.64278760968 = 160.696902422m
452.4m-160.696902422m=291.703097578m
Use pythagorean theorem:

62500-25823.494448025787=36676.505552
= 191.511110779m
arctan(291.703097578m/191.511110779m)≈56.714°
96 → B
substitute w = 12 into the equation D = 3w + 60
D = (3 × 12 ) + 60 = 36 + 60 = 96
# 12 should be the last one
