(5x^a)(bx^2)=35x^8 a= b=

Mathematics
1 answer:
Sonja [21]3 years ago
7 0

Answer:

a=6

b=7.

Step-by-step explanation:

The given exponential equation is;

(5x^a)(bx^2)=35x^8

We multiply out to obtain;

5b(x^a)(x^2)=35x^8

Recall and use a^m\times a^n=a^{m+n}

5bx^{a+2}=35x^8

For the RHS  to equal to the LHS,then

5b=35  and a+2=8.

b=\frac{35}{5}  and a=8-2

b=7  and a=6.

Find the surface area of the figure shown.
balandron [24]

Answer:

The correct answer is option d.  576 ft^2

Step-by-step explanation:

From the figure we can see that a prism

<u>To find the surface area</u>

Surface area = Base area + area of 2 triangles + Two side area

Base area = length * breadth = 15 * 12 = 180 ft^2

Area of triangle = bh/2 = (12 * 8)/2 = 48 ft^2

Area of two triangle = 48 * 2 = 96 ft^2

Area of one side = 15 * 10 = 150 ft^2

Area of two side = 2 * 150 = 300 ft^2

Surface area = 180 + 96 + 300 = 576 ft^2

The correct answer is option d.  576 ft^2
