Answer:
x = 7 , y= - 6
Step-by-step explanation:
4x = -2 - 5y ___(1)
4x= 10 - 3y ___(2)
so, now by simultaneous equations,
10 - 3y = - 2 - 5y
2y = -12
y = -6
if y = -6
then, 4x= 10 -3(-6)
4x =28
x = 7
The like terms in this expression are 6x^4 & 5x^4.
24. The answer is D ,because trapezoids don't have equal sides, parallelograms don't have 5 sides, and they don't all have the same angles. Each side is the same length
Answer:
8
Step-by-step explanation:
66 ÷ a = a + 2, anything that has R2 can also be rewritten to be plus 2. Then if you move 2 to the other side it becomes, (66 ÷ a) - 2 = a. Moving a to the other side will create this equation 66 - 2 = a x a. Therefore, 64 = a ^ 2. You just have to find the square root of 64 then.
Answer:
<h2>Volume = 1659.84</h2><h2>Surface area = 1205.36</h2>
Step-by-step explanation:
Volume for triangular prism = 1/2 * b * l * h
we are given the length and the height but not the base.
since it is a right triangle we can use the Pythagorean theorem a^2 + b^2 = c^2
13.3^2 + b^2 = 20.5^2
176.89 + b^2 = 420.25
b^2 = 243.36
b = 
= 15.6
1/2 (15.6)(13.3)(16) = 1659.84
Front: 15.6 x 13.3 = 207.48
Back: 15.6 x 13.3 = 207.48
Left: 15.6 x 16 = 249.6
Right: 13.3 x 16 = 212.8
Bottom: 20.5 x 16 = 328
207.48 + 207.48 + 249.6 + 212.8 + 328 = 1205.36
