Answer:
d. h(x) = 9x + 35, team with Gertrude
Step-by-step explanation:
Just took the test XD.
But also it is solved by simply adding 4x+20 and 5x+15
Answer:
≈ 660.5 in²
Step-by-step explanation:
The surface area (A) of a sphere is calculated using the formula
A = 4πr² ← r is the radius
Given diameter = 14. 5 then radius = 7.25, thus
A = 4π × 7.25² = 4π × 52.5625 ≈ 660.5 in²
Answer:
x = -1/2
Step-by-step explanation:
(x - 4) * 2 = -9
Divide both sides by 2:
x - 4 = - 9 / 2
Add 4 to both sides:
x = - 1 / 2.
X+1825=y^2
sqrt（1825）=42.8
so the least is y^2=43^2=1849
so x=1849-1825=24
Option A is correct
assuming we use the Pythagorean theorem whose formula is c²= √a² + b²
C being the longest side, a=15 and b=20
c² = √15²+ 20²
c² = √625
c= 25
if you try this formula with the other options it shows it's not a right triangle
