Solve for <span>x </span>by simplifying both sides of the equation, then isolating the variable.<span>x=4</span>
Colder then -7.2 F would be -8.5 F
-7.2 > -8.5
anything to the left of -7.2 on the number line will be less then(oe in this case, colder then) -7.2....so -8.5 falls to the left of -7.2
Answer:
y = 12
Step-by-step explanation:
∵ m∠ABC = 40
∵ BD ray is the bisector of ∠ABC
∴ m∠ABD = m∠CBD = 20
In 2 Δ BAD and BCD:
∵ m∠BAD = m∠BCD = 90°
∵ m∠ABD = m∠CBD = 20°
∵ BD is a common side in the two triangles
∴ ΔABD congruent to ΔCBD⇒(AAS)
∴ AD = CD
∴ 3y + 6 = 5y - 18
∴ 5y - 3y = 6 + 18
∴ 2y = 24
∴ y = 24/2 = 12
Answer:
The height of the trapezoidal base is 7.2 ft.
Step-by-step explanation:
Consider the provided information.
The volume of trapezoidal prism is the area of the cross-section × the length.

Where B is the area of base, H is the length and V is the volume.
The length of the prism is 25.2ft and volume is 1279.152


Hence, the base area is 50.76 ft².
The base is trapezoid.
The area of trapezoid is 
Substitute B=50.76,
in above formula.



Hence, the height of the trapezoidal base is 7.2 ft.
I think the answer is 18 not sure though
