Answer: The area of triangle ΔXYZ is 12 square inches.
Step-by-step explanation:
Since we have given that
RS = 3 inches
XY = 2 inches
Area of ΔRST = 27 in²
Since ΔRST is similar to ΔXYZ.
So, using the "Area similarity theorem":

Hence, the area of triangle ΔXYZ is 12 square inches.
Answer:
Factored form (linear): (4x+3)(x-3)(x-5)
Step-by-step explanation:
Using long division and factoring, we can find the answer. Since the root/zero of <em>5 </em>is given already, we can change this into a factor of <em>(x - 5)</em><em> </em>as 5 is a root.
Step 1: Long division. Divide f(x) by (x-5)
Once you do long division, you should have left over (x-5)(4x²+9x-9)
Step 2: Factor the quadratic
Since you can't do gcf, you have to leave the 4x as a factor. Once you factor out the quadratic, you should get the answer:
(x-5)(4x+3)(x-3)
Step 3: Rearrange (Optional)
(4x+3)(x-3)(x-5)
Answer:
9 sq. units
Step-by-step explanation:
dimensions of rectangle are (7-3),(8-3)
or 4,5
area of rectangle=4×5=20
area of bottom Δ=1/2×4×2=4
area of top Δ=1/2×3×3=9/2
area of right triangle=1/2 ×5×1=5/2
area of Δ HIJ=20-(4+9/2+5/2)
=20-(4+14/2)
=20-(4+7)
=9 sq. units.
or area of triangle =1/2
| 3 5 |
| 7 3 |
|6 8 |
|3 5 |
=1/2[(9-35)+(56-18)+(30-24)]
=1/2[-26+38+6]
=1/2[-26+44]
=1/2(18)
=9 sq. units.
Answer:
2x + y = 173
Step-by-step explanation:
The equation for the stand form of a line is y = mx + b.
You will need
m = slope
b = y-intercept
The question already gave you both of those so you simply put them into the equation "y=mx+b"
m = -1/2
y-intercept = 1
Plug those into "y = mx + b"
Your equation is: y = -1/2x + 1
