Answer:
x = 4
Step-by-step explanation:
f(x) = I x+1 I
when x = -5
f(-5) = I (-5) +1 I
= I -5+1 I
= |-4|
= 4
Answer:
Area of the given triangle = 6.51 ft²
Step-by-step explanation:
If we redraw the triangle as shown in the figure attached we get the height of the triangle as x feet and base = 4.3 feet
Therefore area of ΔABC = (1/2) × Height (AD) × Base(BC)
From ΔABD
sin 53 = AD/AB = x/3.8
x = 3.8 × sin 53
= 3.8 × 0.7986 = 3.03 feet
Now area of ΔABC = (1/2)×3.03×4.3 = 6.51 feet²
Answer:Let's solve your equation step-by-step.
24=x2−4x+3
Step 1: Subtract x^2-4x+3 from both sides.
24−(x2−4x+3)=x2−4x+3−(x2−4x+3)
−x2+4x+21=0
Step 2: Factor left side of equation.
(−x−3)(x−7)=0
Step 3: Set factors equal to 0.
−x−3=0 or x−7=0
x=−3 or x=7
Answer:
x=−3 or x=7
Step-by-step explanation:
The greatest common factor is 3
First subtract the three from both sides
